Shane, I havn't tried that yet. But, after hours of effort to find some clue on this, I find Registry Cleaner Pro under APPData>Roamintg>Systweak>Registry Cleaner Pro>Version 6.1>Partial Backups. Click on Partial Backups gives=RMX file 0000001.rmx and RXB file 0000001.rxb. If I click either, it quickly shows entry in registry but won't open. I think it is an infection causing this. I removed Reg. Cleaner Pro months ago using their uninstall.This file seems to not have been deleted. By the way, I have a PAF program that often asks do I want to backup files and when I click yes, It backups in a folder in my docs. I have 18 gigs to backup and takes long time and I don't want to waste more dvds on a failure. Thanks. Rod
