Rename a file and get a message may cause the file to be unavailable , why?

The problem is that you change the file extension.

If you want to revert back to the way it was before. Please open My Computer--- Tools - Folder Options - View, and check the "Hide extensions of known file types" in the advanced settings below, and OK. That way, it won't happen every time you rename it.

That's because the extension of the file was changed when renaming, so there will be this prompt.

1. You don't need to change the extension (.) when changing the file nameLater) for example. When changing the name, you only need to change 1, if you change the later one. txt will cause the file to be opened in the wrong way, so the file cannot be opened properly.

2. To put it simply, the extension represents the attributes of the file, such as a text document, a vector file, an executable file, and you can know what software the file is opened with by looking at the extension of a file.

You must have displayed the suffix of the file, and if you changed the suffix when renaming, of course, it may not be available. Just hide the suffix and you'll be fine.

Method: My Computer --- Tools --- Folder Options--- to check --- hide the extensions of known file types and remove the checkbox.

Each file has its own extension, in addition to its own name.

Each type of file with that type of extension corresponds to one or more ways to open it. When changing the name, be careful not to modify the extensionOtherwise, the system will not recognize which software was used to open the file.

For example, the jpg at the back is the extension of this file, don't touch it, it will bite you!

It can only be changed"abc"

You can open it in the control panel"Folder options"- View - Hide extensions for known file types The checkmark here is turned on, so that you can rest assured that all the names should be because the extensions have been hidden by the system!

Because you changed the extension of the file.

Workaround: Hide the file's extension.

Turn on My Computer, select "Tools" "Folder Options" "View" on the menu

Find "Hide extensions for files of known types" and put a checkmark in front of it. ok

Since you renamed the file format along with the file format, here's a way to do it.

Open My Computer-Tools-Folder Options-View-Hide Known Type File Extension before ticking --OK.

After that, changing the name will not change the file format, and there will be no such prompt.

This is because the file name contains the file type extension of the file.

For example: or.

Thereinto. jpg and .RMVB is the extension.

If you change the extension arbitrarily, the file will not open properly.

You can hide the extension by ticking the option to show file extension in the system folder options, and you don't have to worry about the file not opening because you have modified the extension.

You can change the name of the file, but you can't move the extension after the name, after changing the extension, the program that called the file may not recognize the file, and the result is that the file is unusable!

What is a file extension? As the name suggests, a file extension is simply the character that follows the file name. If these characters are missing, some files will not work.

For example, *** file is used with a texter, txt file is used with a texter, and so on. You can see how important file extensions are. Without a file extension, your app can't be used.

Similarly, if you modify the file extension, you can't use it. Here, I enumerate some file extensions and the applications that created them. [Note:.]

The following enumerated styles are: Owning Application (Owning File Extension)].

Executable program (.)exe) help file (..)chm) installation information file (..)inf）

You can also change the extension.

For example, the Windows Optimizer installation folder has a file extension named ".".icl" icon file, you modify it to ".".dll", it becomes the icon of the dynamic link library, you use the "display" property to modify the icon function, locate the file to the file you just modified, and then look at it, it is still an icon file.

I agree with the second floor.

Of course, the others are good.

Hello, first of all, this is because when the user makes the renaming, it is the "full name" of the word file that is changed.

The "full name" of a Word file includes both the file name itself and its format (i.e., the suffix extension). For example, although the content of a ** file is the same, the format may be different. Because there are many formats.

The format of the Word file is doc or docx (Word 2007 and above). If the user changes the full name (including the format) when renaming, then Word will pop up a warning: "If changing the file extension will cause the file to be unusable, do you really want to change it?"

Secondly, the solution:

The first option is to change only the part in front of the file extension (i.e., the word file name), not the extension (.).doc). For example, change "to".

The second way is to open "My Computer" and click "Tools" - "Folder Options" in the menu bar.

Then click on the "View" tab in the "Folder Options" dialog box that opens, tick the box in front of "Hide extensions of known file types", and finally click "OK".

At this point, the Word file will not show (hide) the extension. If you want to rename the Word file at this point, just right-click on the file, then select "Rename" in the context menu, and finally enter a new file name.

There are several reasons why your computer's file name can't be renamed

The file is being used: If the file is being taken up by another program, you can't rename it, you need to close the file first.

Insufficient permissions: If the file is in a folder that doesn't have write permissions, you can't rename the file.

Eliminate illegal characters in the file name: Some special characters are not allowed to be used in the file name, such as , etc., if the file name contains these characters, it cannot be renamed.

File name is too long: If the file name is too long and exceeds the maximum length limit allowed by the operating system, it cannot be renamed.

File system error: If there is an error with the file system on the disk, the file name may not be renamed. At this time, it is necessary to perform a disk check and repair the Bibi Knowledge.

If the name cannot be renamed, you need to determine which of the above causes is caused and resolve the problem accordingly.

When we rename a file, sometimes a prompt pops up saying that it can't be renamed, what's going on?

01 When the name cannot be renamed, sometimes the prompt box in the picture will pop up, this situation is because the file is in use or has been opened, so it is impossible to make it clear, the solution is to exit the application associated with this file.

02 There is another reason, your file has an extension, and you deleted the suffix of the file together, so it prompts that it cannot be named. If you don't change the extension, you can't delete it when naming it, which is a little more cumbersome to operate.

03 The solution is to open the explorer and click "Tools" - "Folder Options" at the top.

04 Click "View" at the top of the folder options, check "Hide extensions of known file types" below, and then click "OK". This way, the file will have no extension, and you can change it as you want when you rename it.

The file name of the computer Chinese document is composed of two parts (name extension), and the extension determines the nature of the file, such as the appearance of the word file is "office materials." doc", its extension is doc, which means that this file can be opened by word in the future. Another example is "Paint", a picture drawn by the program is saved as "Sun."

bmp", the extension is bmp, which means that such a file can be opened by Paint in the future.

If you change your name and change or delete the following extensions at the same time, you will see the prompt you said.

The best solution is to hide the extension of the Chinese file on your computer, so that you don't have to worry about changing the extension as well.

The method is: open the "My Computer" window on the desktop, find and click "Tools" in the menu bar at the top of the window, then click "Folder Options", then click "View", find "Hide extensions of known file types" in the advanced settings, click on the small box in front of it, tick it, and then click the "OK" button, and you're set.

In the future, you can change your name however you want, and you won't have to do it again.

Because you changed the suffix as well.

Did you open the file extension?

Just open a folder with Dot Tools -> Folder Option in front of the Hide Known File Type Extension and you're good to go.
