Re: How to put found songs in Song Finder [par MoultiPass]
Very simple.
You install everything here: https://www.voidtools.com/

Then after indexing all your disks (a few minutes, it is very fast), you launch a search for your songs in all the disks (*.sgu), then you sort them by location.

And finally after selecting the right songs, you MOVE or copy them to the right directory. 1 hour max for the whole thing.
