i'm curious if anyone can tell me why fb keeps 'processing' the same files every i start the scanning process.. how does this work? does it actually scan all files in the library every time you hit 'scan all', or does it just compare file sizes from before with current and skips all files it already 'knows'? it tends to take a while, and i'm just dying to know if it's because it has to scan all the files every time, or is behaving oddly
