Checks
/ Files
Unused files
Files
General
Author: Naxess
Purpose
Reducing the overall file size of beatmapset folders and preventing potentially malicious files from reaching the player.
Reasoning
Outcomes
Unused
"path"
Cause: A file in the song folder is not used in any of the .osu or .osb files. Includes unused .osb files. Ignores thumbs.db.
Unused Overridden
"path", likely due to "path with different extension" being used instead.
Cause: Same as the other check, but where a file with the same name is used.
