Sorry, I meant how long do you let the system keep chugging along after it appears to hang? > > I'm not sure 100%, however, I think the bug is somehow related to > displaying the destination folder contents during moving the files. > > > What type of drives are the source / target?

OK, same drive means the entire process is going to be serial; basically this series of steps is pretty much what's going on: 1. Open file for reading 2. Read to cache 3. Close file 4. Open file for writing 5. Write from cache 6. Close file 7. Go back to step 1 And that's ignoring all the "other I/O" the disk is needing to do. Doesn't help any that file open/close is more expensive than just reading/writing a handle that's already open. -- |_|O|_| |_|_|O| Github: https://github.com/dpurgert |O|O|O| PGP: DDAB 23FB 19FA 7D85 1CC1 E067 6D65 70E5 4CE7 2860
