What is MPP file format?

The MPP file format is specifically designed for project management and is created using Microsoft Project software, including Microsoft Project Server. It serves as the native file format for Microsoft Project and is widely used for sharing project data with other applications. Built upon the Microsoft Compound File Binary Format, the MPP format utilizes a hierarchical file system structure to integrate and store various types of data.

An MPP file contains crucial project management information such as start and end dates, duration, cost, resource assignments, and other relevant project data. It also supports the inclusion of project custom fields and customized graphical indicators, providing flexibility for tailoring the file to specific project requirements.

It is important to note that the MPP file format is proprietary and specifically designed for Microsoft Project. As such, it is not compatible with other project management applications, limiting its use primarily to Microsoft Project software.

What is MHTML file format?

MHTML, short for MIME HTML, is a web page archive file format used to save and archive web content for offline viewing. It is a combination of HTML code, embedded images, and other external content saved as a single file. MHTML files can be opened with web browsers, text editors, and other programs that support HTML viewing. MHTML files are commonly used to backup websites, share web page content, or email static web page content without the need for an internet connection. The ability to compress everything into a single file makes MHTML files ideal for saving and sharing web content. Additionally, MHTML files are also easier to manage than HTML files as they contain all of the necessary components for viewing in one file. MHTML files are different than HTML files as the MHTML format includes external content. It also uses MIME encoding which allows it to include binary data such as images, audio, and even video files. MHTML files can also be used to print or save web pages for offline viewing, as the file format contains all of the components for viewing. All major web browsers such as Internet Explorer, Firefox, Safari, and Chrome support MHTML files and can open them in their respective programs. Other programs such as Adobe Acrobat Reader and Apple Notes can also open MHTML files.
