Also, Total Commander shows 3 folders on the main screen, 2 of them are "SD-card" and "Sd-Card(3)", they have the same free space, and the same files inside of them. The first SD Card directory is /storage/sdcard0, and the third one is /mnt/media_rw/sdcard0.
So, how do I get it to work like it was before? I want just one SD-card folder
(And this still happens if I set the ext partition size to 512 or less, so I don't think that matters)
Thanks for the help, and I apologize if what I wrote doesn't make sense, English is not my main language.
(Also, here's some pics of Total Commander, Link2SD and the MiniTool)
