I've used Robocopy for several years now for backup purposes, and never looked back at any backup application I used in the past. I replicate whole valued directories to a removable HD, than from this HD to and equivalent system. Over time, quite a few DLL and EXE have accumulated in these directories, none of which Robocopy can seem to copy to my external HD. Thus, my 2 computers drift apart slowly... Is there anyway, using one of the eigthy-nine (89) switches (or one of the 2^89 - 1 = 6,1897002 × 10^26 combinations thereof) to force Robocopy to robotically copy EXEs, DLLs and other of my "access is denied" friends? Thanks
