Drag and drop from Windows Host cannot handle UNC-Folders -> fixed in 5.2.20

Reported by: BitWorld Owned by: pentagonik
Component: drag and drop Version: VirtualBox 5.1.28
Keywords: Cc:
Guest type: Windows Host type: Windows


Dragging a file from an unc-path from windows host to guest will fail.

The following unc-path:
server\share\resource\text.txt will be translated to: C:\Users\[username]\server\share\resource\text.txt

So the drag operation will fail:

Die Drag-und-Drop-Operation vom Host zum Gast ist fehlgeschlagen. Drag and drop error from host (VERR_PATH_NOT_FOUND). Fehlercode:VBOX_E_IPRT_ERROR (0x80BB0005) Komponente:GuestWrap Interface:IGuest {13a11514-402e-022e-6180-c3944de3f9c8}

When dragging from a drive letter eg R:\resource\text.txt, the drag works as expected. Unfortunately, after trying to drag from an unc-path, the guest and sometimes also the host cannot drag any files anymore and has to be restartet.

This becomes very uncomfortable, when system folders are redirected to an unc-path. So when e.g. the desktop is redirected to:
server\redirected\[username]\Desktop Every drag operation form the desktop will result at least in restarting the guest.

I have observed the problem with 5.1.20, 5.1.26 and 5.1.28 on Windows 10 Pro 1703 as host

Thanks for the report. I've reproduced the issue and working on a fix.

Found and fixed the issue; UNC handling actually wasn't implemented as such. This will be fixed in the next upcoming maintenance version.
