I downloaded Copy Handler because I needed to move 20 GB of small files on my HD from one partition to another, and read in a magazine about this software. So I installed the software, started the move process and left the computer for one hour.
I thought, if someone writes such an elobarate software just for copying files, I can leave the computer and when I come back, I'll be informed about any problems that occurred. My assumption was wrong. Copy Handler stopped working a couple of minutes after I left the computer. The reason: There was a problem accessing a file, and a dialog box appeared asking what Copy Handler should do (Retry/Ignore/Cancel).
It is absolutely obvious that there is a far better strategy if there is a problem with some file: Continue with the other files and collect the problematic files in a list, which the user can work on while the rest of the files is copied in the background. Copy Handler seems to have an enormous amount of copying options, but the fact that this self-evident and time-saving feature was not included (or is not the default behaviour) from the very first version on, is not only disappointing but it disqualifies the developer of this software. Sorry to say that, but it's simply the truth (try to prove the opposite).
