Sample Library doubling up

Hello, After having changed the name of my Samples folder I noticed Cubase didn’t find all the sample packs I previously uploaded. Therefore I re selected the pathway to my sample packs folder and now I have them all back. The only problem is that most of the samples doubled (there are two of each) when I search them in Media Bay, one of the files is empty (no information/sound) while the other one works, I was wandering if there is a way to remove all the inactive files with no information and leave the working ones instead of going from sample to sample and deleting each.
