Let me chime in here.
First off, do you have the Steinberg Library installed? You NEED this installed. From this App, the Steinberg Library, you can find and direct Cubase to all of your Sound Files - AND - you are going on about finding and storing your sound files in App Data, etc.? YOU DON’'T HAVE TO STORE YOUR SOUND FILES HERE - YOU CAN STORE THEM ANYWHERE ON YOUR DAW. Think about it, your Sound Files are typically 28G. Why would you want to bog down your C Drive with Sound Files? Reserve it for Programs. This is one benefit of the Steinberg Library, not to mention it’s listing of all your VST instruments and their individual VST Sound files.
Install the Steinberg Library and then create a VST Sound folder on a different HD. Then copy ALL your VST Sound files to it. After you’ve done this, open the Steinberg Library. From here you can direct it to your new storage folder. Once you’re satisfied everything is there, you can go back and DELETE all other folders containing sound files. (If you’re nervous, just rename this folder so the files can’t be found, and then go back and delete it after you’ve established the new storage path.)
As you open an old Project, and the files you need aren’t found, you can direct a search to the new VST Sound folder you created. You might/will have to do this for every Project you have saved with the old VST Sound path, but all NEW Projects will draw from the Steinberg Library’s location.
