Quick FYI: Go to File -> Add Resource to Library and add your various folders and it creates basically just a folder view from that.

If you have any PDF's in those folder(s), it will show them as a "folder" and clicking on it will then extract the contents as "assets" to drag over to MT. I only cache the PDF results and delete the cache when you close MT as some PDF's could have many large images (like a map folio).

As a side note, if you have any Hero Lab portfolios in those folders, they will also show up as "folders" and clicking them will extract the characters as tokens for use. (here I keep a reference to the portfolio and store the statblocks/images for use in MT. My framework can auto-create pathfinder tokens using the XML data, but that is another post...)
