I'm wondering if files that I add to my notes via Evernote for Mac are also duplicated locally on my computer's hard drive. For example, if I create a note and insert a 20 MB PDF, is that same 20 MB PDF added to an Evernote folder somewhere on my hard drive? Looking in the Library folder com.evernote.Evernote, it appears all notes regardless of content are 4 KB, but I'm wondering if the original file sizes are stored somewhere else. Should I just be using Evernote for Web if I'm concerned about disk space? Thanks.
