How do i fix "Cannot write file..." error?

When I try to save changes I have made I sometimes get this error on one or two files out of a whole album I have just copied. I don’t understand why most of the files save, but those few won’t. The whole album has just transferred with Goldwave in one process, so what is wrong with those couple files? I have tried transferring those files individually without success. I didn’t see anything to help in your suggested topics.

Could you supply some more details along the lines of this request:

Thanks for this, but the correct spelling of this tool name is LockHunter.
