Missing beatmaps

[L9 cancer]

I downloaded a torrent with 80k maps on osu, I've extracted all of the maps, in osu I have 77k maps on osu!std and McOsu detect only 3.7k maps. How is it possible? I've set the right location so I don't think that is the problem. Thanks

McOsu only counts whole osu!standard sets, i.e. a beatmap with 100 difficulties only counts as 1 search result, because of reasons (this will change in the future, but not now). Your beatmap pack probably also has a lot of beatmaps for unsupported gamemodes (taiko, mania, ctb).

I've checked for some maps that aren't packs and I didn't find it. And that 77k maps are for the normal gamemode.

Well, check if osu! has actually finished importing everything.

Keep in mind that even if you close osu!, it will stay open in the background (check via Task Manager) until it has finished writing the osu!.db database file. If your beatmaps have not finished importing, then the database file will be incomplete. McOsu shows whatever is inside the osu!.db file upon loading.

Actually I'm the dumbest person from the world. I had two songs folder, in the first one and readable by McOsu I've had all 3.7k maps, and I've had another folder in the songs folder with all downloaded maps... Sorry for taking your time and trying to help an idiot retarded autistic kid like me. I appreciate your patience btw. Have a nice day and sorry again for taking time with me.
