Ramdisk

This tool is cool

Create a virtual hard drive. 

Choose fixed media.

Then convert to ntfs

convert r: /fs:ntfs

then

rdutil link c:\ramdisk 

link c:\ramdisk to the root of r drive

or 

rdutil link c:\temp\abc TEMP\abc

link c:\temp\abc to the temp\abc of r drive.

I tried system internal junctin.exe command, it cannot link to the ramdisk, but can link the other way.
