Resume file move after Finder crash (unmoved items appear washed out)
The "washed out" items are basically just placeholders that the files were meant to be copied into. Those files aren't anything until the copy finishes and the real files are there. You can safely delete them and start over.

Step one, I would just reboot. This makes sure any copy operations are ended and you know it's safe to delete the placeholders once you've rebooted.

Sometimes Finder gets upset about you trying to delete its placeholders because it thinks they are still in use (busy). If this happens, open Terminal and use

sudo rm -rf /path/to/file/


Replace /path/to/file/ with the actual path, obviously.

That command will allow you to delete ANYTHING, even stuff your Mac needs to run, so make SURE you point it at the right files. They will be gone after this command runs, ignoring all warnings and restrictions. ...but that's fine for these placeholders; you just want them gone so you can try again.
