This article in TidBITS explains how to move from Evernote to Apple Notes, so I thought it would be a good idea to document how to move from Evernote to EagleFiler:
The easiest way is to select the notes in Evernote and then (while EagleFiler is running in the background), press EagleFiler’s capture key. This will import each note into the current EagleFiler library as an HTML file. Any files attached to the note will be saved in a folder next to the HTML file, as separate EagleFiler records.
You can also use Evernote’s “File ‣ Export Notes…” command, although I don’t recommend this because it seems to fail if the note’s title is too long or if it uses certain characters.
EagleFiler’s capture key imports from Evernote using the HTML file format because that preserves all possible data from Evernote. However, HTML files are not directly editable. If you want to edit your imported notes in EagleFiler, you can use the Convert for Editing command (requires EagleFiler 1.8.5b1 for use with HTML files). I’m also working on an importer that avoids the HTML and image files entirely.
EagleFiler is safe for long-term storage because it stores your files in regular folders using standard formats. Your data (and any metadata that you add) is all stored on your Mac and is fully accessible even without using the EagleFiler app.
Update (2018-12-06): EagleFiler now has an improved Evernote importer that creates editable rich text (RTFD) files instead of HTML files. You can also import previously exported .enex files from a command in the File menu.
