Any tips or Tricks for Large file transfer's through RDP

Hello, An issue we are having in our PRA instance is that when we try to do a large file transfer such as an .iso file from our local machine to a remote asset via Beyond trust PRA RDP connection it seems like the transfer will time out\fail before all of the data has been transferred. In general file transfer works fine for smaller files back and forth but we have trouble with large ones. Wondering if anyone has any tips/tricks for copying large files through PRA?
