here's what i've discovered about the windows version. if i modify a file using winamp (or anything else for that manner), mp3tofid immediately recognizes it as a new file (i see 1 empty fids in the summary screen), and deletes the old fid. not sure why.

but the weird thing is... rsync says it only wrote < 10000 bytes, but took 10 seconds to complete after the initial scan. i dont understand whats happening in rsync i guess.
