What is OSK file?

The file in the OSK format belongs to the Game Files category. It was designed by peppy. Additionally, the Game Files category contains 1509 of other files. Osu! Skin Format is most often found on 1 operating systems. The file will work on Windows systems, unfortunately not on others. It is recommended to use osu! to handle this file. This is a program created by peppy.

How to open OSK file?

An often recurring problem with Osu! Skin Format is that OSK is not associated with the correct program file. This is manifested by the fact that OSK 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 OSK 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 osu!

An often overlooked issue is to make sure that osu! is installed on the computer. The easiest method is to use the system search engine by entering the program name osu! in it. 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 OSK files.

Programs to open OSK file

Remember to download programs supporting OSK files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of osu! with OSK files

If the application is or has been freshly installed, but the OSK file still does not use the osu! program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the osu! application as the default for handling the OSK file.

Step 3. Update osu! to the latest version

If, despite the association of the osu! program with the Osu! Skin Format file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the peppy website and install the latest version.

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

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

The OSK file may be unusually small compared to the original file. This is most often caused by a problem while downloading the OSK file. The only repair option is to download the file again.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file OSK or the program directory. Sometimes virus-infected OSK files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the OSK files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged OSK files. The easiest way to restore the file is from a backup or by contacting peppy, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted OSK files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. It is best to move OSK to a different directory.
This problem only occurs with more complex files. In this case, the OSK file is blocked by the first application to open it. Just close unnecessary programs. Sometimes you have to wait for the session to the file OSK to close. However, some background programs may block the OSK file while scanning. If the problem persists, restart the machine.
