it's a program called FileOptimizer. it's free and open source and it basically allows you to put a file through a bunch of different file optimizers instead of just one. it works on a ton of different file formats, however it tends to break some so i'd recommend to use common sense if it's not just an image file you're optimizing https://nikkhokkho.sourceforge.io/static.php?page=FileOptimizer
oh, also, for SVG's, i recommend instead using SVGOMG, since it tends to produce nicer files with even lower sizes than what FileOptimizer does, but it unfortunately doesn't allow for batch file processing. still super useful though https://jakearchibald.github.io/svgomg/
