What is an OSK file?

Skin file used by osu!, a game of rhythm where players tap visual cues in sync with music; contains graphics and sounds that alter the appearance and sounds of the game; used to customize hit circles, the score display, the slider type, the cursor, and hit bursts.

More Information

You can install custom skins by placing them into the \​Skins\​ directory of the osu! game installation (typically C:\​Program Files\​osu!\​Skins\​, but you may have to create the directory manually). If you downloaded an archive (e.g., a .RAR or .ZIP file), you will need to first decompress the enclosed folder and then place the folder in the \​Skins\​ directory.
