I've thrown something together that atleast batch removes systemupdates and replaces moviefiles with placeholders, it can also delete alot more based on simple config files:
i assume that you are saving your games in xexloader / xexmenu compatible path like: USB://Games/Game
you just select the folder usb://games and the program will scan for systemupdates, movies and if available for smart cleaner files (who isn't really that smart

) compatible games

the result:
before:

after:

if your preferred language is not included this will happen:

if you think this is usefull, please test it and write your own smart cleaner files(check programpath/titles/) or click on show available titles in the program... the little button next to it is for finding out the title id via xextool(gonna add the readme in the next release sorry)
