*True* replace? Option to delete all old versions.

I'm working with a client on a site with many many many images/files in the CCK Image/Filefield. Over the course of working with their old Drupal site, they managed to accrue 16GB of images on their webserver! Only about 2GB of that is actual images, the rest are multiple iterations uploaded again and again for their content (_0,_1,..._10,_11,_12, etc, and no I'm not joking...).

I'm wondering if it might be possible to create a "dangerous" option for upload_replace that would truly replace the file and delete all old versions. It would be a flag that would by default be turned off. Alternately, is there another module or CCK option out there I don't know about that would do this?

Thanks!
