It is a standard feature, it's in the "File Upload Mananger", the window that pops up when you manage attachments for a post. There is no setting to change or disable it. The code that does the removing is in includes/cron/cleanup2.php, and it looks like this:
Code:
// Unused filedata is removed after one hour
$attachdata =& datamanager_init('Filedata', $vbulletin, ERRTYPE_SILENT, 'attachment');
$attachdata->set_condition("fd.refcount = 0 AND fd.dateline < " . (TIMENOW - 3600));
$attachdata->delete();
If you remove it or comment it out, then the unused uploads should never be removed.
