There are 2 file types use the .OSZ file extension:
1. osu! Beatmap File
An OSZ file is a beatmap file used by osu!, a free rhythm game in which players click and drag on-screen items in time with music. It contains Zip-compressed data that is used to play music, display graphics, and show players where and when they must interact with the game. osu! players can create their own OSZ files, allowing them to save and share custom beatmaps with each other.
To open an OSZ file:
- In osu!, drag your OSZ file into the game window. osu! will then decompress the file and add it to the game's Songs folder, making it available for use within osu!
- In opsu!, browse to your OSZ file's location and import it. You can also download additional OSZ files from within opsu!
- In McOsu, add your OSZ file to the folder you use as your Songs folder, rename the file to use the .zip extension, and then unzip the ZIP file. The beatmap will then be available within McOsu
You can also view the contents of an OSZ file by unzipping the file with a decompression tool such as Corel WinZip, 7-Zip, or Apple Archive Utility. This will, among other things, allow you to play the MP3 file contained within an OSZ file using your favorite media player.
