I have over 350,000 files in C:\Program Files\SWsoft\Plesk\admin\db - totalling over 40GB. from what I've seen, most/all are .spamassassin_____tmp files (____ is numbers/letters). Can anyone tell me what these are (I assume the copies spamassassin makes while scanning) and why they're stuck? Also, are they safe to delete? This is a Windows 2003 Server environment, no file-level antivirus and the indexing service was stopped post-windows install. Thanks in advance!
