I had Pack and Go'ed an assembly into my PDM vault and now have some duplicate file names. I deleted one of the duplicates and when I try to check in the file that now has a unique name it can't check it in. It is grayed out and says it's not in the vault. If I try to add it to the vault nothing happens. The file I deleted was in a different folder, but I don't remember which one. Now I'm wondering if that's why I can't add the new file to the vault. Any thoughts? It's a simple part. I can easily re-import it or recreate it, but not sure how to get it back into the vault.
I agree with Francisco, login as admin and search for the filename to see if it's in the vault anywhere else. I'm guessing you're on 2015 EPDM or it would tell you where the duplicate file is, so it might also be a problem with what I call "mostly deleted" files that happened in 2015 and before. There was a bug in those versions where it would mark a flag as either deleted from the vault but no the folder or deleted from the folder but not the vault and you'd never see the file but duplicate filename warnings would still think it's there. The solution to that problem is available to VARs under S-065885 so ask them to help you through that if you still can't track them down.
