Getting error message "File in use by another user, locked for editing. No other user actually has the file open. On EX4100

Getting error message “File in use by another user, locked for editing”. No other user actually has the file open.

The user has to create a new document and copy the data over and save it, then delete the original file. This is happening from multiple units configured the same way.

My Cloud EX4100 16 TB on 4 HD’s in RAID 5 config.

What kind of file?

Usually excel or word docs. Office 2013.

It was just reported to me that this is happening from another unit now. Still happening after a system restore and a 40 second reset.

Office usually does that because a LOCK file was left behind. Lock files look like this in File Explorer:

You’ll need to tell Explorer to show hidden files to see them. (It’s the first file in my example, NOT the one that’s checkmarked)

If the lock file is still there and you’re CERTAIN no one has it open, just delete the lock file.
