WinDirStat PowerShell script or registry file to add context menu entries to open on drives or folder, with a little icon. No longer needed with WinDirStat v2.

Thanks for this. Helped me to implement the context menu. The entry for the drive is wrong though, since it would start scanning only your profile folder. You'll need to add some extra backslashes. I also removed the hex-values and used the path names instead.

See my version for a portable setup:

@opus-x Yes, it wasn't working on C: but worked fine on other drives. I've updating the reg file and now it works fine in all cases, including when clicking directories in the left or right explorer panes. Thanks.

This works, and (from a documentation / AI-assisted wiki search I did) the installer has an option to create context menus; maybe it didn't used to and maybe that's the implementation @opus-x refers to. So if the context menu is missing (as it was in my case), reinstalling the newest with that option may fix it.

@earthbound19 As far as I can remember there were no context menus when I did this, but they were added to WinDirStat v2.
