Mapped NAS drive share not working as source

I have Windows 7
WD Mycloud NAS, share “Sharon” is mapped as drive W:
W:\STest is a directory on the NAS share
rclone v1.34
Amazon Drive, the remote is named ADrive
C:\CTest is a directory on the local C: drive

This works:

rclone copy \WDMYCLOUD\Sharon\STest ADrive:Pictures\STest

And so does this:
rclone copy C:\cTest ADrive:Pictures\CTEST

But this doesn’t:
rclone copy W:\STest ADrive:Pictures\STest

It gives
Attempt 3/3 failed with 0 errors and: error listing source:Local file system at \?\W:\STest: directory not found
Failed to copy: error listing source: Local file system at \?\W:\STest: directory not found

Is there a way to work with mapped drives? I can certainly spell out the network name, but I’d like to understand what is going on.

Does it make any difference if you use?

rclone copy W:\STest\ ADrive:Pictures\STest

I would hope it would work!

I know the go team fixed a bug I reported in this area, so if you want I can compile a version of rclone with go-tip and you can see if that works.

I just tried your changed command and got the same errors.

Sure, I’ll give it a try.

Can you try this beta built with go-tip and see if it makes any differenceβ/


Did you ever find a solution to this?
