What is a .OSZ2 file?

An .OSZ2 file is a special type of file used in a free music rhythm game called osu!. In osu!, players interact with the game by clicking and dragging items on their screen to match the rhythm of the music. The .OSZ2 file contains a custom game level, also known as a beatmap, that someone has created to play in osu!.

These .OSZ2 files come into existence when someone who has made their own beatmap decides to share it with others by uploading it to the osu! website. Once uploaded, the game automatically stores these files in a specific folder called the SubmissionCache directory.

To open an .OSZ2 file, you need to use the osu! game itself or a version of the game called osu!mac, which is made for Mac computers. Creating custom levels in osu! is a popular activity. Players can add their own music, design the visual elements, and set up the gameplay challenges. Normally, these custom levels are saved as .OSZ files. But, when you submit your level to be shared on the osu! website, it gets saved as an .OSZ2 file instead. This is also saved on your computer in the game's files.

One key difference between .OSZ and .OSZ2 files is that .OSZ2 files are not compressed like .OSZ files, which means you can't just open them up and change things around outside of the osu! game. This was done to prevent people from tampering with the files. If you want to edit these .OSZ2 beatmaps, you have to do it within the osu! game itself.

At first, people thought that .OSZ2 files would become the main type of file for osu! beatmaps. But, it turns out players like the .OSZ format better because it lets them edit the levels using other software, not just within osu!.
