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.

# Adds shell integration for WinDirStat. The program should be installed in
# Program Files (x86) but it will check if that directory is not on C:
#
# Alternatively, if installed on C: you can use the reg file below instead.

@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.
