Uninstall: New files/folders created by an app aren't deleted

I inherited an MSI install project (MSVS 2010 VDPROJ).  It has normal stuff, DLL's, EXE's, some data files, a few COM registry tasks, 2 shortcuts, and a few parent folders, each with a relatively simple subfolder hierarchy.  Install works fine and the app works fine.  (Note that the install is done with msiexec.exe + a few command line parameters to set custom properties.)  But in running the actual app, some additional/new data files are created and maybe an extra subfolder or 2, all within the defined folders created during the install.  I find that these new files/folders are not removed during an uninstall.  Is there some secret flag/setting in a VDPROJ that I need to set so that ~everything~ is removed?  (I have access to the complete VDPROJ set of files, properties, etc.)  I don't want to have to resort to using ORCA to "fix" the MSI directly.  Thanks for any help.

Files that the application creates after installation are considered user data (e.g. documents) and not deleted by default. You need to populate the RemoveFile table in the MSI or use a custom action to delete the user generated files.
