Sure, this was what I was thinking.
I just wanted to avoid doing this if it already existed.

Ideally the latter, although I don't think in the end it would make any 
difference (as it probably would mean delete them all).

No, this is completely inapplicable for several reasons (data is on a 
Linux based NAS which can only use Ext3, data is already prioritized and 
I'm just talking about high priority, etc...).

I know and I'm using this in several other situations.
However here I'm collecting data from several sources (including Windows 
PCs, so ZFS is out of question).
