Drag n drop to external, another computer on network, another HD, or DVD's.
You can get it all in one swoop by copying your active User account folder.
If you need to split up the data or make the space used even leaner, drag the active User folders: Documents, music, Videos, Favorites, etc.
To copy back into your new install, open the folder, on Organize tab "Select All" then drag the group to the library or User folder on explorer bar on left margin, hold left click until explorer expands to make sure you are releasing file grouping into correct folder.
Fast and easy, no complications or ridiculous space usage.
