I have gigabites of e-mails which I dragged out of EPIM into Windows folders (I like to keep my EPIM file below 500 MB). Viewing these e-mails has always been problematic, full of code in the editor, impossible in EPIM and possible in Outlook, but I don't want that. Now, under Windows 10, I have found that "Crafty EML Viewer" from the Windows app store is very handy. It is not bloated and does only one thing: It lets one see that important mail from 2012 without reading through all the code.
One question, btw: Where are the attachments if one drags mails out of EPIM?
