After releasing a module, sometimes a reorganization of files is performed in the development environment. Regardless of the method used to place the files in the corect locations, some locations will still contain the original files.
For some time DNN has been able to perform a clean up (deletion) of files. This is achieved by including a text file in the PA with the version number in the ##.##.##.txt format and it should list the paths and filenames that should be deleted.
For example to delete the MyFile.ascx file, just include its name in the .txt file. If the file is within a directory like /DesktopModules/MyModule/MySubDirectory/MyFile.ascx, remove the DesktopModules/MyModule path to obtain only a path relative to the module folder: MySubDirectory/MyFile.ascx.
