How to use rclone with phone?

I am wondering how (and if) it is possible to use rclone to sync files to a phone.

I tried this command:
rclone sync "B:\Data\Documents\Music" "PC\Galaxy S6e\Phone\Music" -vv --exclude-from exclude-file-Muziek.txt

But it doesn’t work because rclone thinks PC is a folder.

Is there any way to use rclone to sync between a phone and the local HDD?

Do you have your phone mapped as a drive? How does it appear in an explorer window - what is the path?
