I made my filesytem match my notes system, so I can find stuff.
Joplin has linked notes too, which is nice to link to other things within joplin, but I do two other things too.
file:///Documents/subdir/somefile
and the other way 'round as well.
I have a file extension I made in kde. I cleverly named it... wait for it... dot joplin! :-)
Anyhow, all it does is call a script with:
cat $1 | xargs -I % xdg-open %
Which pulls up joplin with the right note. Right-clicks on joplin notes put the note id in your clipboard, so it isn't onerous to make little files like that for convenience.
