What is GNU file?

The file with the extension GNU is the Text Files file type. In addition to this file, the Text Files category includes 440 related files. GNU Licence Information Format is supported by 3 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Linux, Mac OS, Windows. The main program that supports this format is Sublime Text. This was created by Sublime HQ Pty Ltd. This file type can also be opened by 8 other programs. You can use PSPad, NotePad++ text editor, Atom, Gnuplot in case Sublime Text cannot be used.

How to open GNU file?

The main problem with GNU Licence Information Format is that the GNU file is incorrectly associated with programs. This is manifested by the fact that GNU files open in unusual applications or do not have an assigned program. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the GNU file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Sublime Text

In this case, you should first verify that the Sublime Text application is installed on the computer. This can be achieved by typing Sublime Text into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open GNU files.

Step 2. Create association of Sublime Text with GNU files

If, despite the installed application, the GNU file does not start in the Sublime Text application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. The "always use the selected program ..." field will set the Sublime Text application as the default for handling the GNU file.

Step 3. Update Sublime Text to the latest version

If, however, after binding Sublime Text with GNU Licence Information Format there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Sublime HQ Pty Ltd page and install.

Step 4. Check for the following problems with the GNU file

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. This suggests truncating the GNU file contents when downloading or copying. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the GNU file that we want to open. However, remember that not every infected GNU file can be recovered, so it is important to take care of regular backups.
A typical compatibility error - the program does not support the older version of the GNU file. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair GNU file corruption. The easiest way is to restore the file from a backup, if there is one, or contact
The program can also signal the fact of encryption. The encrypted GNU files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. Copying the GNU file to another location will fix the problem.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes you have to wait for the session to the file GNU to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
