Windows 8 Open Folder With

I decided to switch to a different file explorer. Like how Windows uses Windows Explorer. I will be using MultiCommander. I would like any folders that are opened, to be opened in MultiCommander. How do I do this? Folders could be anything on the desktop, start menu etc. You could also open the folder in other programs such as WinRAR or 7z.

Thanks in advance!

This hack should work for you.

Edit the PATH below or inside the attached .reg file to match the path to where you have MultiCommander.exe

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOTDriveshell]

@="MultiCommander"

[HKEY_CLASSES_ROOTDriveshellMultiCommander]

@="Open in MultiCommander"
[HKEY_CLASSES_ROOTDriveshellMultiCommandercommand]

@=""C:\Program Files\MultiCommander\MultiCommander.exe"" /OPEN %1""
