What are winmail.dat or MSG files?
These files contain email messages from Microsoft Outlook. Since Macs can’t read them natively, users have to rely on third-party software such as Letter Opener to convert and open them.
What is an XPS file?
It’s a document file from Microsoft Windows. On Macs it has to be converted to PDF format to be readable and useable with all built in applications. Letter Opener does that with a simple double click!
