How do you change the destination folder with WD sync? (Win 8.1)

When downloading WD sync I came across a problem with the destination folder. It seems that you can only choose /:C as the destination folder. The problem is, that my C-drive is only meant for OS files and important programs since it’s an SSD with limited spacing. Thus i want to change the destination folder for WD sync to my storage HDD e.g. D or E.

Can anyone tell me how to change the destination folder, so all my files won’t take up space on my SSD?

Thanks in advance!
