What is a .osu file?
File Extension Details
An .osu file is a plain text document used by the rhythm game 'osu!' to define the structure and gameplay elements of a specific song, known as a beatmap. These files contain critical information such as the song's metadata including the title, artist, and creator, as well as timing points that synchronize the game's rhythm with the audio track. The file is structured into several distinct sections, such as General, Editor, Metadata, Difficulty, Events, TimingPoints, and HitObjects. Each section uses a key-value pair or comma-separated value format to instruct the game engine on how to render the level, specifying the exact coordinates and timestamps for hit circles, sliders, and spinners. Because they are saved in a plain text format, .osu files can be opened and manually edited in basic text editors, though most users interact with them through the game's built-in graphical editor. These files are the backbone of the game's community-driven content ecosystem, allowing players to create, share, and compete on custom levels for virtually any audio file.
