We usually drag mp3 files to the osu for creating a map and osu will automatically create a folder for that.
However the name of the mp3 can be quite random. This would add much difficulty to finding a specific song in osu song folder, also making the song folder messy.
If osu could automatically rename the folder to "beatmap set id + ar + ti" (like the format of the maps that you downloaded) after upload, it would be much tidy. Also along with the metadata confirmation policy in osu, it can be quite helpful for the author of the map with a decent beatmap folder name.
