Lillian,
Look to the link below for the .cht file extension listings.

The most probable appears to be the "Generations Family Tree Chart" which can be found at the link below. It looks like you may need to use their software if you really want to view the family tree. Then again, maybe the sender of your e-mail could copy and paste the chart into some other universal document, like Notepad, or Microsoft Word.:

Hope this helps.

I have Windows 98 2nd ed. and Internet Explorer. My computer has lots of memory, etc, but today I received an attachment on an e-mail that was a family tree "Chart". The letters .cht follow the title of the attachment.
I tried to open it with Wordpad but it came up with lots of little squares rather than text. Could you tell me what program I should select to open this please?
Thanks, Lillian
