I would like to have a button that would toggle between two folders, having the same path (except for..) but in two different root directories..
For Eg: The button should toggle between
[b]D:[/b]Folder1\Folder2\Folder3\ and
[b]F:[/b]Folder1\Folder2\Folder3
or
[b]D:[/b]Folder4\Folder5\ and
[b]F:[/b]Folder4\Folder5
etc.
Thanks for any help 
You could create three buttons (LMB MMB RMB)
Three Buttons: A toggle which switches the button between single and multi-function mode. In this mode, the button is turned into a submenu with a maximum of three functions, and these functions are accessed directly via the left, right and middle mouse buttons (rather than through a pop-up menu).
Customize -> right click toolbar -> new-> new button -> right click new button -> three button
Sample button code:
<?xml version="1.0"?>
<button backcol="none" display="both" textcol="none" type="three_button">
<label>Toggle Folders</label>
<icon1>#newcommand</icon1>
<button backcol="none" display="both" textcol="none">
<label>Drive D</label>
<tip>Drive D</tip>
<icon1>#newcommand</icon1>
<function type="normal">
<instruction>Go "D:\Folder1\Folder2\Folder3\"</instruction>
</function>
</button>
<button backcol="none" display="both" textcol="none">
<label>Drive F</label>
<tip>Drive F</tip>
<icon1>#newcommand</icon1>
<function type="normal">
<instruction>Go "F:\Folder1\Folder2\Folder3\"</instruction>
</function>
</button>
</button>
Oops!!
Actually, I wanted something different..
I want the toggle to be dynamic and not specific to a particular path..
i.e. the path, after the root directory does not really matter
In the Eg. I gave,
"D:\Folder1\Folder2\Folder3"
the portion "\Folder1\Folder2\Folder3" can be anything
so,
D:[b][/b]
should be toggled to
F:[b][/b]
I hope I am clear now 
Hi anjan,
got a similar idea like you and eventually did a small batchfile now,
which should do the trick.
Create a button and launch "\ToggleDrive.bat {s}"
Edit ToggleDrive.bat to your needs (change the driveletters, I switched
between C: and D:) and set the path for your dopusrt.exe (within dopus
directory).
Hit the button!.. o)
regards,
rob.
Thanks for your help, tbone!
But, for some reason, it dint work..
Toggle Drive.bat
Button Created:
Error Message that I got:
So, I changed the bat file a bit:
just added quotes to the path
Still it dint work..
i.e. the folder viewed is the same, it doesnt change
But, it did not show the error message
How do I proceed?? 
hey anjan..
obviously you are a serios fan of white spaced file and folder names ?!.. o)
I suggest to quit naming items like this.. it is often and always a guarantee
for hassle of any kind.. o) But.. there's a solution of course.. o)
Now modify the launching, and enclose the {s} in ", like this:
"c:\program files\directory opus\toggle drive\toggle drive.bat" "{s}"
Should do it, tried it here with foldernames containing spaces.
If not.. just scream.. o)
Rob.

It's 2008 not 1975 - time to move on - file/folder names containing spaces are the norm these days.
Users just need to remember to enclose paths in quotes where required.
AWESOME 
Thanks tbone!!
Now it works flawlessly
Just added this..
@runmode hideat the beginning of the button command
so, the dos window does not show up each time it is executed
Cheers!
@anjan
I'm glad you like it.. o)
The @runmode thing makes it nearly perfect, you're right!.. o)
@steve
I know it's 2008, I try to avoid using spaces though. At first place in
foldernames, as it can get annoying if you use shell/cmd often and need
to handle the extra quotes. In filenames, well.. my mp3s contain spaces
at least.. and there are situations, where you simply are stuck, if you try
to escape special characters, need the quotes because of spaces in paths,
and at the same time want the " or ' to be part of a string. I guess you
know what I mean, but hey.. just lemme do it my way, I'm kinda outschool.. o))
