How to change an unknown type file that has been opened with Notepad back to an unknown type

If it's for the sake of aesthetics, it's there.

My Computer》View>Folder Options>File Type>[This Suffixed File]--Delete.

If it's for opening it up and it's easy to use.

Start > Run > regedit found.

hkey_current_user\software\microsoft\windows\currentversion\explorer\fileexts\[.File suffix].

Delete In addition, in order to prevent the landlord from having a painful egg, I will tell you two points of grapevine.

1.If you want to be beautiful, then after you delete the file type, the icon may still not change, that's because the icon reads the cache, and it's useless for you to restart, it is recommended.

Desktop right-click >> >> >> >> >> >> >> >> >> >> >>

Then uncheck "Use large icons" repeatedly

That's it. 2.If you want to find the way to open the association and the icon that the file displays, go to.

My Computer》View>Folder Options>File Type>New>Enter [File Extension]--Advanced [Associated File Type]> to select specifically.

That way, you won't have to look like a big icon with a small icon.

Write so tired Lou Pig give me a few extra points, right?

Just change the extension of the file first,,, as long as you change it to an extension that is not opened by default in a notepad way, and finally remember to change it back to the original one!!

First question:

The default way to open the recovered files.

Open the registry (type regedit in the search bar in the start menu): Hkey Current User Software, Microsoft Windows, CurrentVersion, Explorer, FileExts

Then select the extension of the open by menu you want to modify, select openwilllist to delete the wrong program in the right window, and restart the computer.

Second question:

Tools, Folder Options, File Type, Select Modified File Format, Delete Operation. Create a new file type.

Folder optionsIn the menu bar of the tool, select the middle tab, and then you can find hidden, show file type extensions, etc. As for the previous question, what is your system? XP or Win7? It is not known what exactly the program is.

Open "My Computer", click on the toolbar under "Folder Options", "View", "Advanced Settings" in the big box, remove the tick in front of "Hide extensions of known file types", and click "OK". Then you can see that the suffix of the notepad file is txt, and this "txt" can be changed arbitrarily.

Open "My Computer", select "Tools", "Folder Options", "File Types", then find the extension of the program you modified, and click "Delete". Get.

Select the LNG file, right-click - Run - Select the software you want (tick Always Select).

LNG is usually a language file that can be opened with Notepad, unless you have some other purpose, then I don't know.

Open the My Computer tool in the folder option File Type and find the extension (LNG) of such file and click on the Delete OK.

You've already established a file association, so you can't restore it. You can choose to open it with another program in the running mode.

Solution:

Open a random folder Tools Folder Options File Type Find the ing item and delete it.

Open "My Computer" - click "Tools" above - Folder Options - File Type - find Lights in the box and click "Delete", OK.

Then sign out or restart your computer.

You just opened it, you haven't changed anything, and you haven't saved it, so how can you say "restore"?

The main reason for opening a notepad is garbled is that the file is stored in binary mode, not in the form of a "text file", the way the notebook processes the file is "relatively simple", it treats all the files as "text files", it reads a byte or two bytes of the value and then goes to find the **page loaded by the current system,See what the character corresponding to that value is in the **page,And then display that character。 The file you open is not a "text file" in itself, so how can it be that you know something.

There is no such thing as a "text file" in a computer, and all data is binary. The way the text file is stored is like this, some characters in the ASCII code occupy one byte, and the other characters (like Chinese, Japanese, etc.) are represented by two bytes, it is arranged one after the other, and there are no other structures (struct in C language), so the way the calculator handles the file is "simple".

I'll leave you a question to spark your interest in learning.

In fact, it is not easy to just have a "text file", and there are still many situations to consider. Take Chinese as an example, you open the notepad program, file - save as, you will see that there is an encoding method, there are ansi, unicode, unicode big endian, utf-8 four encoding methods below, you casually save it into a kind and then open it, the display is still what you typed in just now, it's amazing, how does the computer know which encoding method to open the file with?

Make sure you want to use this file first!! If it's a file you don't know!! It may be a file of the system or some software!! Leave him alone!!

This doesn't seem to be able to be restored.,First of all, you have to know that your file is formatted.,And then open it with the corresponding application.。 For example: that Zhang *-wants to forget you, the following suffix is lrc, it should be the lyrics, so you can probably open it with Qianqian mute.

Right-click and select the type of file such as Storm Video and Audio in the Open Method, and open it.

Just change the suffix name, such as: ****

Is it possible to double-click and click to open it with Notepad? It's okay, it's just that a file association has been added, and the file suffix hasn't changed.

If you want to delete this file association, go to the Control Panel, click on the folder option, and click on the file type. Find the suffix of the file you said, click and then delete. Alternatively, you can change how the file opens with this suffix.
