Windows allows you to set Folder locations as Environmental variables. This means you can type the variable name into the Start > Run field (enclosed in percent signs - %Variable Name%) and the Windows browser will open it OR into the Windows file browser path and the folder will be located. Here's how:
At some point you may have tried putting a shortcut folder in another folder, hoping programs like FL Studio, find the data in the shortcut folder. This folder may even have linked to another drive. For example, let's say you wanted the single custom 'VST plugins extra search folder' to include several other folder locations and so you put shortcut folders in the 'VST plugins extra search folder'. Unfortunately this doesn't work. Epic fail! All hope is not lost, the idea was a good one, you just need to create a special type of folder shortcut known as a Symbolic link. Symbolic link folders look identical to regular shortcuts, except they behave as if the data they are linked to is really at the location of the link (but without actually copying the data). Epic win! But only if you can work out how. Here it is...
This will work for Windows Vista, 7, 8 and upward.
A 'Command Prompt' option will pop-up in a list, right-click it and select 'Run as administrator' - You MUST be in admin mode or this wont work!.
mklink /D "DestinationDriveLetter:\destination folder path\SourceFolderName" "SourceDriveLetter:\source folder path\SourceFolderName"
So, we mean something like...
mklink /D "C:\My Files\Music and stuff\64 bit VST\VSTPlugIns" "C:\Program Files (x86)\Steinberg\VSTPlugIns"
NOTE: The source folder name 'VSTPlugIns' can't already exist in 'C:\My Files\Music and stuff\64 bit VST\' since the 'VSTPlugIns' folder is created in '64 bit VST' by the above command.
The new symbolic link folder will look like a regular file shortcut, except the files within it will be visible to any program that searches the destination parent folder. So in our second, explicit example, the folder VSTPlugIns will appear as a shortcut full of files within 64 bit VST folder. NOTE: that any changes to the data in the new symbolic link folder are actually changes made to the source folder also. Delete it in the shortcut, it's also gone from the source.
Sit and have a think for a few minutes what you can do with Symbolic Link folders. The possibilities are endless :)
