What is an OSZ 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.

While osu! is the most popular game that utilizes OSZ files, enthusiastic rhythm gamers have created additional takes on osu!, including:

  • opsu!, an open-source osu! client available for Windows, macOS, Linux, and Android
  • McOsu, a free VR-enabled osu! variant that is available on Steam

Each of those games uses OSZ files. osu! is available only on Windows, so if you do not have a Windows PC, you may need to open your OSZ file in one of the programs listed above.

How do I open an OSZ file?

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.
