How to change excel file extension. Change the file extension. How to change the file extension in Windows XP

Instructions

To create a simple txt file, you will need to launch Notepad. To do this, click the “Start” menu, select “All Programs” from the list, then go to the “Accessories” section and click on “Notepad”. Now make changes to the blank document and save it by clicking the top File menu and selecting Save As.

We've figured out the creation of a regular text document, but we need a registry file (reg). Call the file saving window as described earlier, enter the file name. The file name is required along with extension m, then the file will be determined by the registry editor without problems. You can write File.reg - this will be correct, but on some systems this file may be saved as File.reg.txt.

There is a little secret in the program itself - this utility can save any file format. To avoid confusion with the symbols in the document, enter the following value in the “File name” field: “File.reg”. Quotes at the beginning and end of the file name provide isolation and force the program to save it in exactly the format specified. Because The Notepad program, as well as the Registry Editor, are the default programs; the encoding of the saved file will fully correspond to the files with extension m reg.

If your system does not have problems with extension m files when saving them, you can do it in a simpler way: turn on the display of file extensions and change the extension using the “Rename” command.

Open any folder, click the top menu “Tools”, select “Folder Options” from the list. In the window that opens, go to the “View” tab, uncheck the box next to “Hide extensions for known file types” and click “OK”.

The saved file in txt format must be selected and pressed the F2 button on the keyboard (you can also right-click and select “Rename”), instead of the txt extension, enter reg. Press the Enter key and the OK button.

As a rule, changing a file type means changing the extension in its name - that part that is added to the right of the file name through a dot. Based on the extension, the operating system determines which of the installed applications should work with files of this type, launches it and transfers the file for processing. Usually, when saving the extension, the extension is added to the name by the program in which the file was created. If necessary, you can change it using Windows Vista Explorer.

Instructions

Open the standard file manager for all versions of Windows OS - Explorer. To do this, click a couple of times on the “My Computer” icon on the desktop of your system or use the hot keys win + e (this is a Latin letter).

Navigate through the directory tree to the folder where the file whose type you are not happy with is stored. If you can see the extension of this file in the Explorer window, then right-click it and use the “Rename” command from the context menu that opens. Press the end key to move the input cursor to the end of the name and replace the existing extension with one that matches the file type you want. Then press enter to finish editing the file name. When prompted to confirm the extension change, click “Yes.”

If Explorer hides file extensions from you, then you have a choice - change the setting that forces it to do so, or change the extension in a slightly less convenient way. If you do not expect to constantly change file types, then it is easier to choose the second option. In this case, right-click on the file and use the lowest item in the context menu (“Properties”) to open the “File Properties” window. The topmost field on the “General” tab of this window will contain the full name of the file, including its extension - edit it as necessary and click OK.

If you decide to cancel the prohibition for Explorer to display file extensions, then press the alt key, and in the Explorer menu that opens, select the “Folder Options” line. On the “View” tab, find the line “Hide extensions for known file types” and uncheck the checkbox. Then click OK. After this, it will be possible to change the file extension in the manner described in the second step.

When identifying a computer on a network, the computer data stored in the operating system matters. As practice shows, sometimes users need to change some data in the OS.

Instructions

In the Windows operating system, a computer has its own distinctive data: name, network group name, IP address and serial number of the operating system itself. This data can be viewed and edited if necessary. To find out the name of your computer, launch the system properties window. This can be done through the drop-down menu of the “My Computer” shortcut or through the “Control Panel”. Launch the "Advanced system settings" section and go to the "Computer name" tab. It is in this window that the full name of your computer and the name of the local workgroup will be indicated.

To edit this data, click on the “Edit” button at the bottom of the window. Enter a new name or edit an existing one. Please note that changing the local group will change the network settings for access to other computers on the network. Changes made in this window will take effect the next time you boot the operating system.

To find out your IP address, run the network connection properties. Click on “Local Area Connection” located on the right side of the “Network Center” window. When you click on the “Details” button, all network values ​​for this connection will be displayed. You can change the IP address in the network connection properties.

To see the operating system code, launch your computer's properties window again. The internal system code is displayed at the bottom of the window. You can change it by clicking on “Change product key”.

When identifying your computer on the Internet, what matters first is your external IP address, which depends on your provider. If it is dynamic, then it is set anew every time you connect, if it is static, then you can change it by contacting the provider’s support service.

Any file in computer memory has its own format. In some cases, it can be changed without losing the content of the element. But before you change anything, you need to find out why files are assigned an extension.

Why do files need an extension?

Any file on
at the lowest level is a set of bytes arranged in a certain order. By opening it, we tell the system to read,
separate and display them so that it is convenient for us to work with them. For example, convert these bytes to text on
a certain human, not machine language. The same thing happens with more complex elements: video, music,
programs are initially just a sequence of machine codes.

Extension
file tells the operating system which program can correctly decrypt this set of bytes.
Here are some examples of commonly encountered extensions:

• .txt - the file contains only text; notepad is enough to display it;
• .exe is a set of commands that must be executed to run any
  program;
• .xls - spreadsheet in MS Excel format, to run which you need
  corresponding office application.

Windows has an association system: each file is associated with someone who knows it.
format
program.

Having received a command to open a file with the extension .xls, the operating system launches the MS Excel application, because by default it has an association between these objects.

If you open a file with the wrong application, then some result will be obtained, but obviously not
the one that was expected. Let's say you try to use notepad for the .docx format (it belongs to files
released by Word). The text itself will be displayed correctly because Notepad can turn sets of bytes into
letters and numbers, but underlines, links, highlights, inserted pictures and other media elements will turn into
incomprehensible characters or will not be displayed at all, since the notepad does not know how to decrypt bytes of more complex means
text formatting.

If you open, for example, a .txt file with a program for
displaying videos, you will get an error, since this application will not be able to fit the text bytes to the format
video.

Encoding: how the format helps recognize bytes

If you select the wrong program, you may see strange symbols in the open file
(for example, triangles, circles and others) where, logically, there should be regular text. It happens like this:

The process described above is called encoding: a specific byte is assigned
a certain sign. In each format, the same byte can have its own character assigned, so it is necessary
choose the right extensions.

How to enable file format display

By
By default, in the built-in Windows 10 Explorer you can only see the file name without its extension. This information

opposite the line “File name extensions”. After a couple of seconds, the name of each file will display its format. Extension

Conversion of the simplest formats can be done by renaming the file, for
For more complex transformations, you should use online converters or special programs that produce results without
loss of quality.

The new extension must be entered after the period that separates it from the file name

For example, if the file was called “Crocodile.jpg”, then the result should be
"Crocodile.png".

Via command line (several files at once)

If you need to change the extension of a large number of files, you can run
the steps below to avoid working with each element in turn:

   Right-click on an empty space and select the “Open PowerShell window here” function.
   Large online converters work with almost any format and allow you to perform quite complex conversions

   select the extension to which you need to convert it, and wait a bit, since the conversion process sometimes
   takes several minutes (depending on the speed of the Internet connection, the power of the servers and the file size).

   When saving a file

   Every modern program
   allows you to save the project you are working on as a file. Typically two options are provided: "Save"
   and “Save as...”. The first one is offered for quick saving in a standard extension (each program itself
   selects the standard format) and saves again after making changes.

   The second method will allow you to choose in which format you want to receive the created file. Change the value in the "Type" line
   file" to set the desired extension. In most cases, the application will provide a large selection of formats, but
   sometimes it is limited to two or three or even one
   option.

You listen to audio recordings every day, view hundreds of photos on the Internet, but when it comes to downloading, your computer refuses to open a file. Automatically installed programs do not support a particular format on your PC, or your phone does not open a file with your favorite image? There is no point in despair, and especially not in deleting documents. Learn how to change the file format so you don't lose data.

What is the file format

Information about the contents of the document for you and the operating system of your personal computer is the file format. When you see a certain name of a document, you already imagine what it is - music, picture, book, text, video file. The Windows operating system works on the same principle: having determined the format, it opens the file using a specific automatically installed program. This information is separated by a dot in the document name. In older versions you might have noticed this, but in newer operating systems such data is hidden.

Text documents can be of the following types: txt, doc, docx, pdf, excel, fb2, epub, djvu. Some are created using Microsoft Word and are suitable for writing articles, abstracts, and dissertations. Other formats are more suitable for reading books electronically. Types of graphic documents – jpg, jpeg, png, rav. The first pair is suitable for viewing regular raster and pixel images on a computer or phone, and the second pair is suitable for large-format printing. Video files can look like: avi, mp4, flv, mpeg, wmv. Audio audio tracks – mp3, wav, la (Lossless), m4a (Apple Lossless).

How to change the text file format on Windows 7, 8, 10

Manually renaming the names of file formats of electronic documents will not work, because Windows 7, Windows 8, Windows 10 automatically hide this data. Remember that subsequent changes must be appropriate for the document type. For example, from “doc” to “docx”, from “m4a” to “m4r”. Otherwise, the computer will give you an error. To change the extension, follow these steps:

• You will need a menu. Go to Start / Control Panel / Appearance and Personalization / Folder Options.
• Open the “View” window, scroll to the very bottom, where we find “Hide extensions for registered file types.”
• Uncheck the box.
• Hooray! You can easily change text files in the name itself.

Using online converter programs

There are simpler solutions that programmers have invented. If you don’t want to dig into the settings to uncheck the box, and it’s more convenient for you when the extension is automatically hidden (after all, you don’t need to constantly edit it when changing the name), use special converter programs that can convert the extension in a matter of minutes. Here is a list of them for PC:

• WinScan2PDF – converts all text files into PDF format.
• Total PDF Converter – converts PDF documents to Doc, Excel, Text, HTML or CSV.
• ABC Amber Text Converter is a program that processes a huge number of formats: WK4, RTF, PDF, HTML, TXT (Unicode and ANSI), RFT, DOC, SAM, XLS and others.
• BookReader is suitable for avid readers, especially when you really want to study a new work on the way to work or school, but there is no way to take an e-book. The program makes DOC, FB2, HTML, RTF, WRI, TXT, CHM formats readable on the phone.

If you don't want to download utilities onto your PC, no problem! You can choose online converters that do file conversion in a few minutes. Often there you only need to register and upload a text, audio, video file. Here are some examples of services for converting e-books: ebook.online-convert.com, convertfileonline.com, popprograms.com, lamerkomp.ru.

Programs for changing audio and video file formats

While you have not yet downloaded the conversion program, you can change the display of music files, as in text documents (uncheck the box so that the extension is displayed). The only caveat that stops it is that the quality may be lost. This is very disappointing if you downloaded a song for a fee in excellent resolution, but your PC detects the format as unknown or unacceptable. Use the Format Factory program. It is universal in use and the question of how to change the format of a video file, audio, DVD, MP4 will be solved instantly.

Converting graphic file formats

You have several options. The simplest one is to click “Save As” and set the required format for the new document. If you have graphic editors on your PC, for example, Photoshop, Corel Draw, Adobe Illustrator, then you can do the conversion like this:

• Open the program, upload your photo there.
• Click "Save As" and install the desired extension.
• Don't forget to set the image size to the appropriate size.

The Corel Draw program is designed for vector graphics, logos in excellent quality, it is better not to upload regular photo formats there. If this option does not suit you, use special converter programs (Format Factory, Paint, Microsoft office) or online services: photoconverter.ru, online-convert.com, pcfreetime.com, image.online-convert.com.

Sometimes it becomes necessary to change the extension of several files at once. For example, let's change the extensions .txt on .html .

This method renames all files in the folder. Clamps shift and right-click on the empty folder field.

We select the “Open command window” item, after which a command line window appears. Next we enter:

ren *.txt *.html

And press Enter. Everything is ready, the files are renamed.

This method is very convenient, for example, when all photos from a camera automatically come with the extension .JPG, and we need .jpg .

How to change the extension of one file

It should be mentioned right away that the file extension plays a critical role in determining how and with what this file will be processed or opened. Those. if you take a picture with the extension .jpg and change to video extension .avi, That This file will not open on startup.. You can only change extensions that you are sure of. For example, to translate from .wma V .mp3, or from .mpeg V .avi you need special programs called converters.

In this article we will look at a simple way to change the extension by renaming it. All files have extensions that are indicated after the last dot in the file name.

For example: Text.txt

To rename, you just need to right-click on the file, select “rename” and change the entry after the period.

For example: Text.html

If you don't see any extensions for your files, then they are simply hidden by the system. To see the extensions you need to go to:

On Windows XP:

Start → Control Panel → Folder Options → View tab →

On Windows 7, 8, 10:

Start → Control Panel → Folder Options → View tab →
→ uncheck “Hide extensions for registered file types” → OK

Also in Windows 7, 8, 10, you can go to the “View” menu in the way shown in the picture.

Good afternoon, dear readers, today I want to tell you how to change the file type in Windows in a minute, this topic can be considered a continuation of the previous post about file associations in Windows 10, as it complements it. In my example, we will consider such operating systems as Windows 7, Windows 8.1 and of course the top ten, where would we be without it now. I am sure that this information will be very useful for novice computer users, especially if your computer was attacked by a virus that changed all file associations.

Types of file formats

Let's first understand what types of file formats are. It is logical that every program installed on your computer, no matter what operating system, opens its file, and it is logical that it does not need other files from third-party programs, since they have their own openers. It follows that the files must somehow be different from each other, and identify themselves for a specific application. They didn’t think long and came up with the idea that each file of a certain program would have its own format or extension. The extension is what comes after the dot at the end of the file name.

Examples of file format types

Here are the most common file formats:

• Sound > have the extension mp3, wav, flac
• Videos > have the format avi, mkv, mpeg and so on
• Executables > have exe, msi format
• Archive > rar, zip format
• Text > doc, docx, txt, pdf, etc.

There are a lot of such categories, each of them contains its own types of file extensions, you can see all of them in the note above about associations, I advise you to read. There are times when you need to quickly change the file format, for various reasons, a simple example: you have a picture with a png extension, and on the website, avatars for uploading to your profile, for example, can only be in jpeg format, what to do, you can, of course, convert it online, but The Internet is not always available, so we come to the point that we must understand and figure out how to change the file type in Windows.

I would like to note that to convert formats, you need to use either online services or specialized software, the examples below are for informational purposes only

Let's move on to practice and look at how to change the file type in Windows 10. Suppose I need to change the txt extension, in any operating system of the Microsoft family, extensions are hidden and it is logical that if you need to change something using standard means, then you need to enable the functionality.

All we need is to open Explorer, this can be done by clicking on the folder icon to the right of the start button.

We can change the format by clicking on the View menu and checking the File name extensions checkbox.

Please note that you can enable Windows 10 hidden files here. We check everything, our txt. That's it, now by selecting it and pressing the F2 key, you can change the format to the desired one, erase the txt and replace it. A real case when this can be useful is when you write some kind of script in txt, and then change the format to bat or cmd and it becomes a script.

As you can see, changing the file format in Windows is no more difficult than saying one, two, three, but don’t think that this always works, you won’t be able to take an mp3 and make an avi from it, miracles don’t happen. This method is useful, for example, when editing the Hosts file in the system, since it does not have an extension by default, and there are cases that when editing it, the user is asked to save it in txt format, which is not always visible if display is not enabled.

Let's further analyze how to change the file type in Windows 8, this version is a little older and not so widespread around the world, in my opinion, it was rejected in vain at one time, if it weren’t for it, there wouldn’t be dozens of them, but that’s not what we’re talking about :) By default, Windows 8.1 does not display extensions in the system, for example, I have a picture and I need to change its extension, but it is not visible in the title.

To fix this, do the following: open Windows Explorer (any local drive on my computer). You will have such a convenient menu at the top, in it you need to go to the View tab and check this box, File name extensions. This action will allow the operating system to enable display of file formats or any file extensions.

Let's take a look at our file again and lo and behold, it has .jpg in its name, this is its format.

Now, what you need to do, there are two options, the first is right-click and select rename from the context menu, but you are already an advanced user, so you know that the same thing is done if you press the F2 key on the selected file. Next, you will have the opportunity to edit it, erase the old format and write a new one, for example png, in the window where you are asked for confirmation to change the formatting, click Yes.

As a result, you received the desired extension. As you can see, a couple of mouse clicks. Now you know how to change the file format in Windows 8.

Very often people tell me that the article is misleading, that nothing works. Here I want to note that people did not read everything completely, and apparently did not pay attention to what I wrote, that this does not always work and not with all formats, and in other cases you need to use special services and converters to change the file type.

Let me give you an example from life: government agencies very often still have Word 2003, and it has the .doc format, but most offices already have MS Office 2013, which by default has the Word file type *.docx, which in 2003 will not work, so the method indicated above easily changes formats, and you can easily transfer the desired format to a user with an old office.

And so we’ve figured it out in figure eight, let’s see how to change the file type in Windows 7, here it’s slightly in a different place.

The described method for seven through the control panel is also suitable for tens and eights

I have an archive file, it is in rar format, I need to change the file extension in Windows 7 to zip, this is also an archiver. By default, seven also does not display formats, so it needs help with this, so to speak, a little tweaking :)

We have two methods, each of the below should open the Folder Options snap-in. The first method is to open Start > Control Panel.

In the upper right corner, in the View item, select large icons, and then look for the Folder Options icon, it is its capabilities that will allow us change file type in windows.

You can also get to the Folder Options menu using this method: open my computer, as you can see there are no additional buttons at the top.

Press the magic Alt key and you will eventually open a hidden menu. In it, click on the Tools button and then Folder Options. Choose for yourself which method you like best.

Go to the View tab, where you need to uncheck Hide extensions for registered file types. By removing it you will be able to change the file type in Windows.

We all check our archive, select it, press F2 or right-click to rename it, and set the desired extension.
