I’ve had luck exporting large groups of notes from EVERNOTE to DEVONTHINK, which is EXCELLENT. I choose ENEX format and it exports to the finder. Then I drop that single file containing many, many items into DevonThink, and the individual files appear in the DevonThink database.
However, they each come in a folder that ALSO contains a HTML file. Any way to eliminate that extra file? I tried de-selecting “Source URL” in the export menu. but to no avail.
