This forum is great. I've learned so much about FDISR just reading the posts. But another thing puzzles me. Archives use NTFS compression. I did a test of starting a restoration process and stopping it half way through. The drive space used to decompress the archive wasn't released until I rebooted the PC. So I was wondering if this was normal for XP, the NTFS filesystem, or FDISR is somehow keeping file handles open accidentally.
