A client has been using a QNAP TS-469L (f/W: 4.1.0) for over a year now and recently, for no apparent reason, he can't save modified files.
If he opens a Word, or other editable file that is residing on the QNAP volume, modifies its contents and then tries to save it, Windows announces that the file is being used by another application and refuses to save it.
This is the case for all workstations.
I tried copying a from the QNAP to the users desktop, and then back again; same error, it won't overwrite the original file
I have opened a ticket with QNAP but thought someone might have already come across this situation
Any ideas ?
