Unavailable through an honest mistake, possible, that's why most OSes nowaways<br>
have a trashcan system (and digikam implements its own, as it has to work<br>
across OSes). On restore, the data is reread, including sidecars (if it is<br>
removed from the database on moving the files to thrash).<br>
<br>
But a local file *cannot* be "unavailable just for a short moment", contrary to<br>
files on a network share (esp. WiFi) or removable media.<br>
<br>
And to avoid all misunderstanding, I'm talking from my experience (under<br>
Linux) and not in any way connected with the Digikam maintainers/coders.<br>
