Hi everyone, hope someone can clear up this mystery for me. I am running windows 7 64bit and backup is run automatically. Recently I got a message saying I didn't have enough memory for the backup to proceed so I went into the backup and deleted all but one record. That gave me plenty of free space except it told me the last backup had not completed. I deleted the last record and proceeded to do a full backup. I have a 500Gb external drive where the backup is held (I think! it has a file that looks like a ext HDD with my computer name but the file reads "EMPTY") When I go into computer the ext drive reads : Total Size = 465Gb, Free space = 52Gb yet when I select all the files and right click the ext drive, properties, it reads : Free Space 23.3Gb. When I go into Backup and Restore, click manage space, I get : data File = 149.98. System Image = 238.87Gb. Other Files = 26.64Gb. It appears this backup has taken almost all of the memory of the external drive and the file I believe is the backup file is empty and yet all the files add up to 23.3Gb. Can some one please explain this and advise how I can recover some of the space.
