Cannot read file attributes ERROR

[krectus]

Hi, new to this program, seems great, just what I'm looking for. I'm trying to backup my WD NAS folders to the backup USB drive plugged into it but I'm running into a problem. So far I tried copying over a folder with about 200 video files, it managed to mirror about 150 of them fine, but with the other 50 or so I'm getting this error.

Cannot read file attributes of "x.mp4"
ERROR_UNEXP_NET_ERR: An unexpected network error occurred. [GetFileInformationByHandleEx]

Can't make sense of why it would work with some and not others, they're all similar sized video files.

It makes .tmp files in the destination folder the same size as the original just doesn't seem to be able to complete the file copy or something.

I'm using the latest version, just downloaded yesterday. Anyone run into a similar issue or know of a fix for this? Thanks, hoping someone can help cause otherwise this seems like a great program.

EDIT: Tried copying one of the files that didn't work to a different folder, renamed it "Test.mp4" and it seems to mirror fine now. Maybe some weird problem with this program and certain file names?
But tried it with a different file and it didn't work.
