My guy/gal, MAM is one of the easiest places to get a good ratio because it mainly based on getting point from seeding. Actual upload is gonna be pretty low. Just download a bunch of ebooks is you are low on space and just seed. Literally download like 100 ebooks (probably less than 50MB total in space and you’d get like 50-80 points an hour and then you can easily build up ratio by buying upload credits. Lets say you are seeding enough to net you 100 points and hour, if you seed a full day that’s 2400 points and you can buy quite a bit of upload credit for that. If you download more free leech stuff then even more points. I love MAM and its incredibly easy to build ratio this way

The cmd route should work. Done it many times doing like .mp4 to .m4b. You go I to cmd (command). Type the following: cd “FILE-PATH” (without quotations). Hit enter. Then type: ren *.file-type *.file-type Example would look like: ren *.jpg *.PNG This woukd be renamed the files all from jpg to png
