Ever try to use the copy and paste function to move an entire hard drive worth of folders?
I doesn't work very well. If it encounters an error it will stop, leaving you to start all over again.
XXCOPY
The installation program integrates it with the Widows command line.
To copy an entire folder the syntax would be:
xxcopy c:\somedirectory f:\anotherdirectory /backup
The entire contents (including folder structure) of (somedirectory) will be copied to (anotherdirectory).
