I would very much like to be able to capture filepaths via drag and drop.

try this tcl/tk plugin https://github.com/megrimm/pd-dnd-plugin

Will it work in linux? It appears not. Should have mentioned I'm on linux.

@schitz you can probably build for linux by guessing stuff from the windows instructions. just use the linux equivalents of the msys2 packages
edit: maybe there is some platform-specific tcl/tk code but I would still try it

@schitz As specified in the pd-dnd-plugin readme file , you have to get tkdnd by cloning or downloading https://github.com/petasis/tkdnd.git
But, even more simpler, there are release files where you can get binary files for every platform, without need to compile : https://github.com/petasis/tkdnd/releases/tag/tkdnd-release-test-v2.9.2

Thanks guys, I got it working. Maybe one of these days it'll be added to PlugData! I mentioned it to the dev and he said he'll eventually have a look.
