How to add a virtual drive or U disk directory for the local folder In Sync WD?

Such as the title.
I found that you can only add a directory on the hard disk, you can not add a virtual drive or U disk directory, how to solve this problem?

Hello,

I haven’t try this. Let’s see if any of the users can share some information about it.

Thank you! Estimated that the program does not support, may need to increase the WD virtual disk support.
