I have my mp3 files on a NAS and would like to open a Dos Command prompt in the directory of the track I've selected in MP3Tag. I added a new action and pointed to the exe in C:\Windows\System32\cmd.exe. When I right click and select the action a dos box opens but I get: 'CMD.EXE was started with the above path as the current directory. UNC paths are not supported. Defaulting to Windows directory. C:\Windows\>' How can I fix it so that cmd.exe open in my chosen directory? ---

Try to add the NAS-path as a windows drive so that you can address it with a drive letter (instead of the \\servername\folder notation). Use the Explorer function "Add network drive" (my translation) for that. ---

Yes, that works. Thank you 🙂 . Just wondering if I can get away with not using mapped drives. More research needed I guess ![:book:](https://community.mp3tag.de/uploads/default/original/1X/0036d5b68f6226c53f6c68abfd0a7b8096fd4505.gif ":book:") ---

I just tried: /s /k pushd "%\_folderpath%" as the parameter set and it does work in that it assigns a temporary drive letter and opens a command prompt in the desired directory. So getting much closer. ---

See if this Microsoft Knowledge Base article helps. Apparently cmd.exe simply doesn't permit UNC paths to be passed to it as a guard. This behavior can be disabled with a registry entry. I just tried it in Windows 7 and it works for me. [http://support.microsoft.com/kb/156276](http://support.microsoft.com/kb/156276) ---
