When you open My Computer you see floppy disk drives, hard drives and DVD drives. Lots of space is wasted in that window and you have to click several times to reach the location that you wanted to. If you do have folders on your hard drives that you use over and over again you might want to consider creating folder drives which would make them appear as drives in My Computer.
The main benefit is of course that you can access those folders much faster without having to click several times. Windows has a build in command line tool that can do this but I prefer to use XSubst which has a graphic user interface and offers the same functionality.
The user selects an available drive letter in Xsubst and clicks on the Connect button afterwards. This opens a Browse for Folder window. Just select the folder that you want to display as the drive letter that you have selected before. Those links between the drive letter and folder are not permanent unless you press the Permanent button in XSubst.
The permanent setting and the drive letter can be removed again in Xsubst as well. I use Xsubst mainly for two folders that I access several times a day, saves me some time every time I access them this way.
