What is a .OSK file?
The .OSK file extension stands for an osu! Skin File. This type of file is associated with osu!, which is a rhythm game where players need to tap on visual cues in time with music. The .OSK file contains various graphics and sounds that can change how the game looks and sounds. This includes customizing elements like the hit circles, score display, sliders, cursor, and the animations that appear when you hit notes correctly.
To use these skin files in the game, you need to add them to the osu! game's installation folder. Specifically, you should place them in the \Skins\ directory. The typical path for this directory on a Windows computer is C:\Program Files\osu!\Skins\. If this folder doesn't exist, you might need to create it yourself.
If the skin file you have downloaded is compressed in a .RAR or .ZIP file, you first need to extract the contents of this archive. After extracting, you can then move the resulting folder into the \Skins\ directory.
The primary program that opens .OSK files is the osu! game itself. Once the skin files are placed in the correct directory, you can select and apply them within the game's settings to customize your gameplay experience.
