Using Windows Explorer, I can click on "Computer" select my external Backup_HDD drive, click on the archive image, click on the slice and see all my files, including my normally hidden boot files. My internal drive is C:\ The archive data is shown as having the C: address (but not C:\) From Acronis I can "Explore" my archive. Acronis causes Windows Explorer to open up, just like I described above. No difference. If I mount the image there will be a new drive letter assigned during the Mounting session, such as L: Is the reason to mount the archive the recommended way when copying files from the archive image so that there is no confusion which could be caused because to the drive letter? ... say copy *.* from drive L: to drive C:\?
