bhudgeons / Evernote Folder Action.scpt
Created August 22, 2012 05:12
AppleScript that creates an Evernote "drop box" for files.
(*
Works in Evernote v.3.3.0.
(Note: I've read of people having problems with
AppleScript with the AppStore version of Evernote.
If you're having trouble, you might want to sync,
then delete the appstore version and download the
mac app directly from Evernote.)
