What is the .MAR File Extension?

.MAR File Extension Description:

The file extension .mar is most commonly associated with the archive created by Mozilla, which stores bzip2 elements (in Compressed Binary diffs form) produced by implementing variations of bsdiff. The .mar file extension is used in the delivery of update packages emanating from the update system, and contains a series of files including an index positioned at the end. The file structure of .mar file extensions includes a Header Section, followed with a list of length files with the Index Section at the trailer, containing the list of length entries. The decision in pursuing a proprietary format like the .mar file extension was based on the premise that is an easier option that generated fewer codes.

The file extension .mar is used by the Microsoft Access application as a Report Shortcut file, created by the Microsoft Access database. This application is an RDBMS that is a component of the Microsoft Office Professional productivity suite, which operates by combining a graphical user interface with the Jet relational database engine. The .mar file extension benefits programmers and small enterprises alike, with its customized handling of relatively small tasks.

It is also used in the development of professional applications, especially in standalone and prototype programs, that can be used by a sales force on the road. Aside from the Microsoft Access, another product of the company that utilizes the .mar file extension is the MSN program, which uses the format as an MSN Archive file. The file extension .mar is used in this context for storing HTML, bitmaps, and other web page related contents.

The file extension .mar is also used as a Bibliographic Data Format by the MARC 21 communication application, which is a standard implemented for the exchange and representation of bibliographic, classification, authority, and similar contents. The .mar file extension has three components; the content designation, the data content, and the record structure.

The file extension .mar is also used as an Attributes Records file by the Pegasus Mail application, which is an e-mail client that is executed in computers that are running Microsoft Windows Operating System platforms. The .mar file extension contains attributes records for every user of messages contained in the Public Folders, or previously referred to as System Wide Folders.
