How to capture "movable" Ref. AVIs

How to capture "movable" Ref. AVIs
If you want to make "portable" Ref AVIs (where you can move the AVI
and corresponding data files without breaking the Ref AVI) try the
following: 
1) Map a virtual drive to your target directory using the SUBST
command. For example, to map virtual drive Z: to D:\Video 
SUBST Z: D:\Video 
2) Capture as Ref AVI to the _virtual_ drive. Example, capture
Z:\Z_Capture000.AVI 
You should end up with Z_Capture000.AVI and its data files (ie,
Z_Capture000.000, Z_Capture000.001, etc) in D:\Video 
3) For subsequent captures to the same location, you don't need to
do anything - just capture to drive Z: 
Now, if/when you need to move the file... 
1) Un-map drive Z: 
SUBST Z: /D 
2) Map drive Z: to the new location of the Ref AVI's data files
(say, we're moving to E:\Saved_Clips 
SUBST Z: E:\Saved_Clips 
3) Move the Ref. AVI and its data files to the new location 
MOVE D:\Z_Capture000.* E:\Saved_Clips 
Things to keep in mind: 
1) You probably want to run SUBST every time you boot up.  Make a
shortcut to the SUBST command with appropriate parameters and put it in your
Startup folder.
2) It's helpful to put the virtual drive letter somewhere in the AVI
name so you know what drive it's looking for. 
3) All Ref. AVIs that were saved to the same virtual drive must stay
together for them to work. In other words, if you have two Ref. AVIs that
were captured to virtual drive Z: and you move them, you'll have to move
them both if you're using both of them, otherwise the AVI that didn't get
moved will not be able to find its data. 
4) You can't use a physical drive letter as a virtual drive, so
leave yourself a few letters in case you add more physical drives in the
future. Start from Z and work your way down.
