        Optionally patch assets directories to have a trailing indicator character(s) in their names for easy identification
        The patch is done when ASSET_DIR_INDICATOR environment variable is set
        Without the patch, the FileSystem::DirExist() reduces its accuracy and the FileSystem::ScanDir() only scans for files
