What is PC Win: Err Msg: The Folder Conversion Program?


Hi - I think this is a follow-up to your mime answer on 22 January. Periodically I get an e-mail which has an attachment that the sender thinks he has sent normally, but comes out at my end as "winmail.dat". This is always a product of Outlook. I use Netscape - not sure if this has any bearing. If I ask them what they sent, it doesn't seem to matter (text, photos...), and when I ask them to resend it as a Word or JPEG or whatever, it comes through OK. Can't seem to find an explanation for this nuisance. Thanks for the help. Walker Butler
