MHT File Format

MHTML document (Microsoft)

MHT is a Web page archive file format. The archived Web page is an MHTML (short for MIME  HTML) document. MHTML saves the Web page content and incorporates external resources, such as images, applets, Flash animations and so on, into HTML documents.  

In Internet Explorer, when you save a Web page as a Web archive, the page is saved as an MHT file.  Any relative links in the HTML (those that don’t include all information about the location of the content but assume all content is in a directory on the host server) will be remapped so the content can be located.

MHT files open in Internet Explorer or, with an add-on, in Firefox and some other browsers. MHTML  Converter is one program that converts MHTML files to regular HTML.

Because MHT files can be infected, they should always be scanned before opening.

MIME type: message/rfc822

MHT files are a great way to save a web page, and they can be opened individually in your web browser. If you have dozens or hundreds of mht/mhtml files, you will probably need a specialized MHT viewer, since it becomes inefficient to open/close documents in a browser just to see whats inside. A viewer I like is MHT Viewer, http://www.mhtviewer.com, which lets me open, search and convert mht files into pdf. Thanks again for the article!

I received an email containing a photo already visible (nothing to click) but the photo was shown upside down. When the "Save as
drop down box appeared, there was no choice to save it to My Pictures as a .jpg file so the photo is useless to me.

I wanted to email a file to my colleague but office 365 cant recognize the file. I thought it is a Microsoft file and outlook should deal with it with ease :o
