Preview "EML", "PST", ."dat", for "eM client", "Thunderbird", Outlook (Partially Solved)

[donatopace]

Hello,
i have partially solved problem to Previem "EML" mail messages under "Everything" but attachments inside are missing,

Can you find solution to show attachments inside the email message?
Can you preview also other containers: "PST"(Microsoft OUTLOOK), ".dat" (eM client)?

Attached file is a Registry Key to enable Preview only of "EML" files:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.eml\shellex\{8895b1c6-b41f-4c1c-a562-0d564250836f}]
@="{92dbad9f-5025-49b0-9078-2d78f935e341}"

[void]

Everything uses the system to render previews.

Third party preview handlers can be installed.
Maybe there's a preview handler out there that supports attachments.

{92dbad9f-5025-49b0-9078-2d78f935e341} is the built-in internet explorer preview handler.

Can you preview also other containers: "PST"(Microsoft OUTLOOK), ".dat" (eM client)?

Currently, no.

The registry key I attached uses exactly this value but the attachments are not displayed!
-Is there another value or a third-party plugin to solve problem?
-Could you develop compatibility for "PST" and ".dat"?
-If you do, could you tell us within how long?
If the time is short I will make a donation of €500.

I'm doing a lot of previewer research, but found no eml previewer, which also displays attachments.
My Solution:
Thunderbird is set to use the Maildir format, storing all mails in single EML files.
I always detach attachments in Thunderbird into a dir reserved for it,
The files in this dir are content indexed in Everything.
So I have the full EML content and attachment content available for searching in Everything.

This is only for MSG files and not free.
It's not applicable to Thunderbird.
