If you run the above query it will do nothing because in VB4.2.2, there is no filedata in the attachment table. KH99 is correct though, you will need a script that will query the filedata table for file sizes, filedataid, and userid. Then it will have to traverse the file system using the attachment folder hierarchy and delete the files and thumbs, then go back and "clean" the attachment and filedata tables as well as scrub the posts that reference the attachments if you want it to be done correctly. There may be a couple more tables to be adjusted as well, but I haven't researched it that much.
