By "target directory", I mean, the location where you are copying
from or
to.
Are you copying files from windows to /mnt/sda1 ?
Usually, the ownership of /mnt/sda1 is root:root, so you can't just copy into it.
only commands such as [sudo x11vnc -forever -loop -ultrafilexfer], when combined with UltraVNC's vncviewer.exe, can achieve file transfer functionality
This means you CAN transfer files, right ?
But it cannot be copied and pasted, only VNC-Viewer-7.13.0-Wdows-64bit.exe and TightVNC's tvnviewer.exe can achieve the copy and paste function!
Are you expecting that by dragging files from windows, it'll just pop up on TC desktop ?
If that's the case, that would be a total different issue.
You'll need a much heavier desktop environment.
