file extension?

Hello,
I have a backup program that is not finding Windows Mail files.
What is the file extension for Windows Mail and where does it reside please.
TIA

It's mostly .eml, but also .email. It also uses .nws and a few more
extensions
for news and index files.

To find them, click on Tools, then Options, then Advanced, then Maintenance,
then Store Folder, and it will tell you what directory it uses for this.
Click on
Cancel, then Close, then Cancel again.

If you want to back up the email, I suggest you back up the entire
directory,
not just one file extension from it.

I know about identity in outlook express ,please tell me about windows mail how it is?

You're asking, how is the identity feature in Windows Mail?
It isn't.
Windows Mail does not have identities like Outlook Express did.
By default, all email from all accounts goes into the same Inbox.
There are four different ways of changing that:

1. Use separate Windows user logins. That gives total privacy.

2. Use message rules to filter incoming messages into
separate folders.

3. Upgrade to Windows Live Mail which has separate folders for each
account, no rules needed: http://download.live.com/wlmail

4. Purchase an add-on called WMIDs:
