Portable Opera using Windows virtual drive
Friday, 1. June 2007, 14:49:33
- Create a folder with name Portable Opera anywhere inside another folder. Say, inside C:\Applications
- Inside Portable Opera folder, create a batch file (Mount.bat) with the following
SUBST Z: "C:\Applications"
and another batch file (Unmount.bat) with the followingSUBST Z: /D
- Run Mount.bat and this will assign physical path C:\Applications to virtual drive Z:
- Run Opera installer, select your preferred install type as Custom, then destination folder as Z:\Portable Opera, check Only use single profile for all users and complete installation.

NOTE: If you use classic installer, you have to select installation directory as Z:\Portable Opera & uncheck Individual Opera profiles for each user on this computer.
To run Opera, launch Opera.exe from virtual drive Z:.
Run Mount.bat to create virtual drive Z: & Unmount.bat to remove it.
You can place Portable Opera directory anywhere and run Opera by changing the physical path in Mount.bat.
Suppose, if you move Portable Opera directory to F:\My Documents\Programs, in Mount.bat change
SUBST Z: "C:\Applications"to
SUBST Z: "F:\My Documents\Programs", run Mount.bat and then lauch Opera.exe from virtual drive.
Warning: Don't run Opera from physical drive.

What's the advantage compared to Opera Portable, OperaUSB, Operator or Opera4USB besides you can do updates yourself?

Hi Tamil,
Do you know, how to make a virtual CD-ROM drive visible inside My Documents folder? It can be done with a physical drive using Win Drive Management Snap In, but virtual drives are not visible there. It's required to see the drive content (say, to run Opera from a CD image)in a public place, where access to new drive letters is blocked, and only My Documents folder is visible in Save As or Open dialog boxes.

Hi Tamil.
Just curious. What happens if I run Opera from physical drive?

Hi Tamil
Another question. Can I use this method to install any other portable application?
Thank you

How can I force Opera to install the profile directory under the main program directory. I have one installation like that, but don't really know how it turned out that way.
