I mean, here's what I find in the directory for my current comics project:
a bunch of Illustrator files (this is what I draw it in)
a few CBZs of the content
some PDFs of the same content
a bunch of web-res gifs of the pages
some Indesign files (related to publishing the book)
a couple .csv files used in an Indesign data merge
various other gifs/jpgs/tiffs
a Word doc
a link to an external directory full of print-res TIFFs
Plus a subdirectory structure to chunk all of this into stuff related to book production, model sheets, fan art, and whatnot.This is the use case where every "We're going to replace and simplify the file browser!" effort seems to fall down. Recognizing that real people's projects sprawl across many file formats.
