MHTML File Format

MHTML document (MIME)

MHTML (short for MIME HTML) is a file extension for a Web page archive file format as saved by Internet Explorer. The archived Web page is an MHTML 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 MHTML 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 MHTML files can be infected, they should always be scanned before opening.

MHTML files may also go by the extension MHT.

MIME type: message/rfc822

I received an e-mail picture from a friend and proceeded to save it. Evidently I did something wrong. I cannot open the file to view it.

Many "new tab" pages come and I can't work. System restore did not eliminate. In recycle bin I saw HMLHTL files. Don't know what they are and a Nasa-FBI alert I was locked. I don't get this???ran46@frontiernet.net
