Word is emptying it for you. That's what they're doing in the Trash
Word writes a temporary file into the OS's Tmp folder for each documentit
opens. It then maintains it by appending each edit you make to the end of
the file, during your edit session.
If Word exists normally (i.e. You quit it without error...) it cleans up its
temp files.
If it crashes, it doesn't clean up.
Each time Word starts, it checks its temp folder: if there's anything in
there, it presents these to you as "Recovered" files.
You need to check the recovered versions against the saved versions: ifyou
are saving your work regularly, the recovered version (saved during themost
recent Auto-Recovery save) can be older than the saved version.
Once you have decided which version to keep, Word will then place the
discarded recovery files in the trash.
You would need to login with root access to see the contents of the temp
folder. I wouldn't bother: Word will clean it up for you ‹ so will the
operating system.
Cheers
