Iam sure this question was made a 100 times, but i cant find it.
i want to transfer a single mp3 file with no folder to a folder in the same place, i have tried several actions but it moves all the files, even if i put the only file in mp3tag per example

If you include parts of (or the whole) in the filename definition, you move the file to that folder.
Use Convert>Tag-Filename and e.g.
Format String: %artist%\$num(%track%,2) _ %title%
This will move the file to a folder named like the artist.
