You can only use the RemoveFolder element to remove empty folders, so that won't help much. If you have a CustomAction that creates files in your application directory, I suggest you don't create RemoveFile elements for those. Oftentimes, you're going to create subfolders with disposable data in your application directory and you'd have to create removal elements for every file that is added to the directory. The lazy way to go about this is to make use of the RemoveFolderEx Element. As described on that page, you have to use the Remember property pattern to make this work.

      REMOVAL_CMD
