By default, Windows Explorer opens showing the My Documents folder. To change the default setting so that all top–level drives and folders are shown, follow these steps:
1. Click Start, point to Programs, then Accessories, then right–click Windows Explorer, and click Properties.
2. Under Target field, which reads “%SystemRoot%\explorer.exe” add “/n, /e, /select, C:\” to make the line read “%SystemRoot%\explorer.exe /n, /e, /select, C:\”
3. Click APPLY, OK.
I love that little trick. Now when you open Windows Explorer you get to choose from all the folders and drives, not just My Documents.
