move files to sd card via symbolic links

for quite some time now I have been trying to move data from my internal memory to the sd card, as my internal memory is always filled to the brim.
As apps like Link2SD have either not worked or randomly stopped working, I want to take the same approach as I would on a Linux machine; Just making symbolic links.
The problem I am having is that I seemingly cannot make a symbolic link to my FAT32 formatted sd card. When formating the sd card to something else, like EXT4, the system doesn't mount it automatically anymore.
There is of course also the option to change the mountpoint of the sd card to /data/, but that of course doesn't work on a running system.

Long story short: How would I go about changing the mountpoints? On normal Linux systems you could edit the "fstab" file, but on my android system there is multiple fstab files which all have different rules inside; None of which fit the actual mountoptions that are seen in "mount".

I would like to keep to the official rom, as I have gotten quite used to it over the years and don't want to wipe my data to install something else.
Of course I have full access to all partitions. (at least as far as I know). I know my way around systems like debian and ubuntu, but have fairly little idea about android.

Well it is not possible to do that i think, FAT32 with ext4? No not possible, also a SD card can't be formatted to ext4 easily (Only works on some models of SD cards), but you can do a few things here:

1. Get a EMMC upgrade from local repair shops with all the data backed up from the old EMMC
2. Try other apps to link SD cards
3. Get a better/compatible SD card
4. You can actually use the built-in tool to do that, take a look:

Hope this helps! If it doesn't, get back to us with some more details.

Happy Hacking!
