how to avoid losing data (stored files)

[UR user]

I believe this has happened a few times.

1. I open up a UR database.

2. I open up a stored file to edit externally.

3. Somehow UR closes while the externally edited file is still open and being edited. This can happen because of a crash, or I mistakenly shut down UR not realizing that one of my many open windows is a stored file.

4. I save that file.

5. Later I reopen UR (sometimes after a reboot) and notice that my changes to the stored file have been lost.

My question:

* Is there anyway to recover the saved file (I believe that the temp directory gets wiped after UR shuts down).

* Is there any way for UR to warn me before closing that there are stored files that are "open" and still edited? That way I would know not to shut down UR or to finish editing and close out those items?

* Is there some way to keep an archive of these temp files (limited to say 50 MBs) so that once I realized the error, I could go back and recover the saved embedded file.

Thanks for any reactions.
