MimeMan is an application for RISC OS which provides a graphical interface to the MimeMap file on your computer. The MimeMap file is extremely important and governs how the operating system and applications interpret files when they are transferred to your computer. If you've ever received an email with a PDF file which shows as a Data file, or had trouble downloading a program from the internet, then the culprit may well be an incomplete or broken MimeMap file.

MimeMan allows you to easily examine and alter MimeMap files, whilst ensuring that the file is properly constructed. It can work on any file you choose, including the default system file and a MimeMap file which is provided online as a reference file. This file includes various useful mappings which are not present in many default configurations.
