Hi AllenM,
My first Idle full system scan ran fine. Started manually, it took 4 hr 51 min, 800K files (about 326 GB of data). Scan time was about an hour more than using my previous version, which is cool since it logged history unattended.
Thanks for your helpful advice regarding using Idle scans and the new version, it was instrumental in resolving my issue. My appreciation and best wishes to you.
