Not all files will move from folder to folder

[ajajoy]

When I try to move files from one folder to another (or off a device on to my computer), not all of them move. I have tried drag & drop, and cut & paste. I don't get an error message or anything like that, some of the files just don't move. So I have to go through file by file and see what didn't make it, very tedious! I have tried moving as few as 25 at a time, and they still don't all make it. Can anyone help?

Seems like some were in use by something.

Anyway, can you try using Fastcopy? (this is the official website with download, select Executable (32bit), yes the guy making it is japanese, don't worry about the download page being in japanese, the program is in english)
It's simple and does usually tell you why it wasn't able to move files, so you can have a clue of what is going on.
For moving lots of files, it's much better than copy-paste/drag&drop. Also because of its options (as explained on its site).

In case of other problems, report back.
