I have the stranges effect. I sync my ebooks via syncthing between my machines. The source in this case is my macos, targets are two cachyos systems. On both of them the epubs are extracted an on the second cachyos I could verify that indeed the extracted files have been synched from the other cachy machine but for some reason luckily not back to the macos machin. What exactly is extracting the I could not figure out and I have no Idea hat exactly is destroying my files.
