Yes, there is a double directory structure, so you can get to the files either through their true path, or their 'virtual' path. What are you trying to do? The only real difference is formatting, which I think you had in your original post. You can't 'format' a SUBST drive, because it's already part of another drive.

Drew, It's not like a blank drive - it's just like a drive letter... And I need a drive. Virtual drive with a logical drive letter. With file structure inside it. Real file structure. In the case of SUBST a drive letter is assigned to a directory. And files (or subdirs) are created within the file structure of the physical disk, which directory is used in SUBST... A virtual disk has its own file structure. Like RAMDisk. But RAMDisk uses RAM to simulate a disk and a virtual disk uses a file.
