What is a MIM file?

A MIM file is an encoded file used by email programs that contain 8-bit data or other characters besides the US ASCII character set. It supports 8-bit content, such as file attachments, instead of standard 7-bit messages typically sent over email. MIM files also include metadata, such as the MIME version, content type, and encoding method.

More Information

MIM files may appear as part of an email message or included as a separate attachment. Email applications often decode the files automatically, but you may also decode the files with utilities.

A MIM file may also be a keyboard layout definition file used by IBus (Intelligent Input Bus), which enables multilingual keyboard strokes to be input in Unix operating systems. It stores a configuration of a keyboard in plain text that is used to define the mapping between keyboard strokes and functions performed in Linux. MIM files may include letters, numbers, special characters, typographical symbols, and unusual diacritics.

You will most likely only encounter a MIM file if you are a Linux user and modifying or adding a keyboard layout with IBus. For example, if you enjoy constructing languages that utilize special characters not available on a typical keyboard, you may create or download a MIM keyboard layout for use on your Linux machine.

You may also convert .KLC files created with Microsoft Keyboard Layout Creator to MIM, since Linux does not support KLC keyboard layout files. You can use the "ms2mim" program to convert KLC files to MIM files, which can be used with the M17 library in Linux.

If you are a Linux Ubuntu user, you can add a MIM keyboard layout by following these steps:

  1. Download IBus and the M17N library, then run sudo apt install ibus-m17n to install them.
  2. If it does not already exist, create a new directory ~/​.m17n.d with mkdir ~/.m17n.d.
  3. Copy and paste the MIM file to the ~/​.m17n.d directory.
  4. Run ibus restart.

You should now be able to access the keyboard from the "Settings" page under the "Other" language.
