Send To Windows Copy
Occasionally (especially with flash drives) I find that the copy process fails. What I do when this repeats is copy using Windows then use Teracopy to test by skipping existing files. If the program had an option to send the current list to Windows and then test after that would be great in still managing the structure of the folders/files to be copied and still get the testing done.
If the copy failure issue is eventually resolved then this suggestion would not be needed.
Thanks in advance - keep up the good work!
