They say necessity is the mother of invention. That explains it. I have a laptop that has a partitioned drive and way back when I got it, I installed SVS to the 30gig system drive without really thinking about installing it to the 80gig partition. Now several months—and about 15 layers—later I've gotten to the point where I want to move the FSLRDR directory from my C: drive to my E: drive because I'm running out of space.

There are several juice articles that explain how to do this manually but let's be honest; moving all the layers manually is a pain. Being the lazy person I am, if that were my only option, I'd just keep letting layers take up space on my smaller drive until I was forced to act.

That's why I wrote SVSDriveSwitch, which is a relatively simple batch file that will do all the work for you. SVSDriveSwitch loops through all your installed layers and exports them, deletes the old layers, changes the registry key for the redirect area, and then re-imports all the layers for you. It's not the most efficient way to move redirects, you probably won't want to push this out to fix multiple machines, but it is the simplest approach and gets the job done with relatively little work on your end—which is what's really important.

Set up and Use

SVSDriveSwitch is simple to use but there are a few things you need to know:

1. The download file is a .txt but you need to rename it to a .bat file for it to work
2. The script exports all the VSAs to the folder the script is in, so I recommend creating a new folder wherever you like though I don't recommend the root of any drive, I've seen SVSDriveSwitch try to import VSAs that were in other locations on the dive when you do that.
3. The default drive that the script moves the FLRDR directory to is E:\, because it's the drive I wanted to use. If you need a different drive you need to edit the batch file and change this part E:\fslrdr under the REG command (it's the third to last line of code) to what ever drive you want.
4. This last part is very important, you need to restart your system before you can use your moved layers! The driver needs to reload with the changes that were made and if you don't you'll get 1040 errors because SVS can't find the layers at the old location.

Notes and Tips

• SVSDriveSwith doesn't delete the old FSLRDR directory, I decided to leave that out since I didn't want to do anything complicated and could expect that C:\fslrdr would always be the directory that needed to be removed.
• If you're moving the redirect to a different drive because of space, remember that the VSAs that get exported are saved to whatever location SVSDriveSwith is ran from. So if C: doesn't have room, just run the script from the new drive that has the space.
• This process can take quite a while depending on the number of layers you have in SVS and their size. It's probably best to run it over a lunch break or overnight because Exporting and Importing can be processor intensive and slow down the system.
• Lastly, SVSDriveSwitch doesn't prompt you for a reset so please remember to do so.
