Version: (using KDE Devel) Installed from: Compiled sources I often copy huge amounts of files I don't want to loose and always copy them and then compare source and copy with kdiff3 /Beyond Compare (Win32 Shareware, runs on wine) If the kio system would have an additional option to safely copy/move files which performs a CRC check on the written data I would save a lot of time and work, and always could be sure my files reached the other disk intact... whoever reads this first: give it a tought. Should be a simple one.
I would recomend using md5sum (or some other *sum) instead of a diff'ing app, but I agree that it would be a nice feature to have, although I suppose this could only work on some backends.
For such cases, i.e. making backups, rsync or some other dedicated GUI tools are a better option, IMHO.
