Foobar Organization (remove pdf & album seperation)

I want to use foobar to organize my audio library but when I go to move folders having move entire content selected it removes my pdf files. I tested it to see if maybe it would just land in the recyle bin and I could salvage it from there however that is not an option I would like to know if there is a simple way to preserve these with out manually moving them all (or utilizing a restoration program due to everything being moved around probably overwriting the files previous location thusforth having to move it all to another source and ya still a pain there after). Second off is there a way I can sort the audio by artist and album without getting it split up by featuring artists as well? I kind of doubt this is possible unless I go through and name them with the ft artist info in song title. Thank you!
