You could easily write a little script file that copies this folder to another drive. I have a script that does this on a regular basis, just in case I forgot to do it manually. 
interesting , how is this script done … thanks sam
Assuming you have Windows, create a file with the file extension .js and place the following code inside the file:
(You adjust the folderDestination string variable to where you want a copy of the VST Presets folder. Don’t forget to keep double slashes as dividers.)
var folderSource = ‘C:\Users\[Account Name]\Documents\VST Presets’;
var folderDestination = ‘C:\Users\[Account Name]\Documents\Test\’;
// The fso object interfaces with the file system (hence the name).
var fso = new ActiveXObject(‘Scripting.FileSystemObject’);
// This ensure that the VST Presets doesn’t contain any old files.
// If you rather the ALL files are kept, just remark the line out. (Add // at the beginning of the line.)
fso.DeleteFolder(fso.BuildPath(folderDestination, fso.GetFileName(folderSource)), true);
// This copies the source folder into the destination folder.
fso.CopyFolder(folderSource, folderDestination, true);
complex but thanks …s
