QNAP can't save modified file (in use)

Hi

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 ?

thanks
yann

is anything of the folloing true:
- disk full?
- quota depleted?

in either case no new data can be written. Quota would be user centric, disk full would be generic.

well no and no
and besides, the users can save their file under a different name

Apparently it is solely linked to PDF files
If the user closes all the explorer windows, he:she can then save & overwrite the source PDF file

hm. almost sounds like a hidden app window is still blocking those files.
or maybe some preview functionality?

Not sure though. I have a QNAP, but no windows systems available.

In fact it was the windows Explorer's preview pane that was locking the PDF files
Windows requires Acrobat reader to preview PDFs and therefore the file is considered 'open' by the acrobat module
All works corerectly once you disable the preview pane
