I've changed the Efficion Articles module from VB / WSP to C# /WAP and I need to remove all the old .vb files. I'm using the cleanup component in the manifest and it works fine for files in App_Code/Articles but doesn't work at all for files in DesktopModules/Articles.

I've tried using both the manifest format and a separate cleanup file. I've tried it in both DNN 6.2.6 and 7.4.2. Nothing worked. I've quadruple checked everything and can't get it to work.

What am I missing?
