for yahoo it tells me to edit the "emote_user.dat" file... HOW DO I EDIT IT?

If that's all it's telling you, I'd try using notepad.

How can i read the contents of ".dat" file and make modifications to it?

There's no way to answer that without knowing the application that created it.

Please tell me the meanings of this extension when it comes after several types of files.

Thank you.

Hey Leo, I received a .dat file through e-mail from a Immo-office, they told me it should be opened with Acrobat Reader, but it doesn't seem to work. I replied them with telling them that I couldn't open it and then they just sent it again.
Could you please help me?
Thank you very much

An acrobat reader file is a ".pdf" file ... I've not heard of them using ".dat". Either the sender is doing something wrong, or their mail program is. Ask them to either send their mail as "plain text" with the attachment, or if they have some other way to get you the file.
