I want to reach the disk space limit of my iPod touch to handle the 'no space left' condition in my app. In order to do that, I've been sending big files to fill the space of the disk.
I send the files with iTunes, but somehow the memory limit is never reached. It seems that everytime I try to reach the limit with these transfers, iTunes is automatically copying older files from my ipod to my macbook in order to create space for the new files. At least it seems so, but I'm not sure. Something else could be happening but I don't know what.
My iPod touch is on iOS 9.3.5 and I have the latest macbook pro.
