To help explain, I kind of have folders split up for downloads monthly or there abouts numbered or names different months. So when I select all the missing files and try to relocate, it only seems to pickup the couple of files that might only be in that same folder.
Another issue that may be effecting this I've noticed is some files might be doubles so when it searches it stays missing but says it's already found in that location or something. So maybe this stops or effects all the other files being located or something?
