Replying to Computer help for my work

Alright so the secretary was on our sever, and try to move files from her computer to the server, but had a file open half way through the alphabet, so only half went, but then an error came up and she had to close that one file. She did this, but then it asked if you want to redo it, and clicked yes, so she lost h-z becuase she thought it would start from the begininng not where she left off. Is there anyway to get the files back? There not in the recyling bin, on either her comp, or the server comp, should be looking on the server computer to restore it, or in her computer? Thanks for the help if you can shes really bummed out right now becuase it was about 1,000 files!
