I recently started moving all of my Evernote content to DevonTHINK, but have encountered a bit of an issue: when importing large notebooks (over 100 notes), only a fraction of the total notes are imported.
For example, a notebook with over 500 notes in Evernote winds up with about 130 notes in DevonTHINK when imported.
Are there any fixes for this? For now, the best solution I can think of is to move a small number of notes to a separate notebook and import in small chunks (though this will probably take a while).
Try doing the export from within Evernote then importing those files.
Thank you for the advice Jim; I did some more testing and it looks like the problem was on Evernote’s end. Some notes had a permanent sync issue, and when the importer hit one of those notes, the remaining notes in the folder would stop being imported. Solution: delete all Evernote notes from the hard drive and re-download.
Looks like people have been having this issue with Evernote for years, but so far no fix.
The good news is that DevonTHINK’s Evernote importer is now working fine. 
You’re welcome and thanks for the follow-up (and unintentional vindication!
)
Glad to hear it’s working now. Cheers!
