Open OSU File
The OSU file extension is primarily associated with 'Osu!', a popular rhythm game developed by Dean Herbert. These files are traditionally used to store levels, also known as 'beatmaps', for this game. Unfortunately, as OSU files have a distinct structure and purpose, they can't be opened by just any application. In this article, we will explore the formats and ways to open and use files with the OSU file extension.
Osu! Beatmap Files
Osu! maps or 'beatmaps', as they are more commonly known, are the levels in the 'Osu!' rhythm game. Each beatmap file, with a .osu file extension, corresponds to a specific song and level of difficulty in the game. These beatmap files are usually saved in a text-based format, containing information about the song, such as its title, artist, version name, and the beatmap author. If you would like to open and use these files, you will need the ‘Osu!’ game itself which you can download for free from the official website (https://osu.ppy.sh/home).
Osu! Skins
Besides beatmaps, OSU file extensions are also utilised in customising the appearance of the 'Osu!' game. Players often use Osu! skins, collections of graphics and customised gameplay settings, to personalise their experience. These skins stored as .osu or .osk files can be loaded into the game leading to different game appearances. Resources for creating or downloading preexisting skins can be found on the official Osu! website or on user forums such as (https://www.reddit.com/r/OsuSkins/)
Osu! Tatakae! Ouendan
Another use of OSU files is found in 'Osu! Tatakae! Ouendan', a Japanese rhythm game for the Nintendo DS. Here, the OSU file extension represents the save states from this game. Unfortunately, these save states with the .osu extension can only be used with compatible DS emulators.

OSU File Important Information
As noted earlier, the OSU file extension is unique to specific games and their respective emulators. Hence, you should avoid opening such files with random applications as they may fail to interpret the content correctly, leading to possible data corruption. It's best to use the official 'Osu!' software or respective compatible DS emulators as advised.
