Files that contain the .mim file extension are most commonly associated with email message files. These files are known as Multipurpose Internet Mail Extension files.
The MIM files are used by a variety of email applications to support 8-bit email content such as file attachments and audio and video snips. This makes it possible to send emails containing more than just ASCII text characters.
An MIM file may be included as a part of an email message or they may be sent as a separate attachment.
Files with the .mim file extension are identical to files that contain the .mime file suffix. The majority of email applications can read files with either of these file extensions.
