Where do I find the smartware.swstor file?

I know I have found this before but today went to the C: program files to the WD folder - it is not there. When I go to my C: not the program files just the C drive to the WD folder, that states that it is empty. I recently updated smartware to most recent version. Thanks. 

Hello, the “smartware.swstor” folder is saved inside the external hard drive, this is the folder that Smartware creates to save your files. 

I believe to actualy see the folder, if you right click on the My Book icon, and “open”,  it comes up with that file. Thanks anyway.
