I have previously successfully used Acronis to recover a whole disk. However, when trying to recover an individual file, it doesn't work. I am using the Explore Image option and get the following fatal error: "Cannot assign a drive letter to a partition from the image archive." My backup is on a NAS drive, and I am trying to restore a file onto the C: drive of the PC from which the backup was created. The PC is running Windows XP Home, and the Acronis version is 8.0 build 796.
