Alright I have a fun little problem. I am moving a user to a new computer in that process I need to move that user's PST file, their PST file is 5.6GB. They are running Office 2003 so the PST file's size is no issue. The problem is that I keep getting the Cannot move file "insufficient space" error. First there is move than enough space on both drives. 18.6GB on 1 and 55.8GB on the other. At first I attempted to move it across the network at night, just got the error. So I then removed the disk from the old computer installed it in the new computer as a slave drive and tried to copy to the new drive, again the same error. Both drives are NTFS. I have tried several different ways to move it. All the same error. What am I missing here? I have been working with and on computers for over 20 years so save your time and mine and avoid the simple answers. Unless it's one of those simple little things you may think I have overlooked. Thanks in advance for the help!!!
