Thunderbird mail storage.

Thunderbird under the hood I can find some interesting files. I could identify a few of them;

On a Kubuntu 8.10 system the Thunderbird profile and email box is stored in $HOME/.mozilla-thunderbird/someprofile.default

For example:
$HOME/.mozilla-thunderbird/izvwsxcs.default/

The default profile can be set in the file $HOME/.mozilla-thunderbird/profiles.ini

Here is an example:
[General]
StartWithLastProfile=1

[Profile0]
Name=default
IsRelative=1
Path=6wpi8gaz.default

[Profile1]
Name=Nicholas
IsRelative=1
Path=izvwsxcs.default
Default=1

In example above, my profile is izvwsxcs.default. In that folder, you can find that the emails are stored in the email box oscc.org.my
$HOME/.mozilla-thunderbird/izvwsxcs.default/ImapMail/mail.oscc.org.my

Emails are stored into two files (in above folder).
The email contents: A file with no extension
The email header: A mail summary file (.msf) extension
