I'm new to MultiCommander, maybe I don't know yet all of the many features. As IT employee I have often to work with other devices, so I use often mappings to network shares. I miss functions to connect network shares to drive letters. I know that you can simply start the "map network drive wizard" (known from Windows Explorer) with the following command:
Rundll32 Shell32.dll,SHHelpShortcuts_RunDLL Connect
I think I could create a user defined command but maybe this would be of public interest and could be generally included to MC.
Unfortunately there is no known command to show the disconnect network drive wizard (known from Windows Explorer) but right-click on a drive letter in the drive bar will show the disconnect command for this single drive.
