Unfortunately this doesn’t work correctly if a file is in more than one folder. You get a mess like this:
L1 - All Papers/TWLA Reading Group/Wishlist,All Papers/Teaching/Leiden Course S02,All Papers/Teaching/Leiden Course S02/FInal Selections/Silvio 2019 - Puppets, Gods, and Brands - Theorizing the Age of Animation from Taiwan.pdf
Other software can’t read this. I don’t know what the best solution would be, but some options might be to (a) only list the first path to the document (since other apps generally don’t need the other info), (b) list each path on a separate line, or with clear markers between them (i.e. don’t do this: “folder 1, folder 2” in the middle of a path, and don’t use symbols that might be in book titles like commas to separate entries), or ( c) export the PDF with the RIS file in its own attachment folder (this is what Zotero does).
