The MIM file extension is a type of Multi-Purpose Internet Mail extendable Message format which stores information pertaining to a particular email message. It contains attachments, email headers and other specifics including message content, sender, recipient, and other information which is saved in the email’s header fields. The files use the Hypertext Markup Language (HTML) formatting, and can be created in different operating systems and various email clients, such as Outlook, Windows Live Mail, Mozilla Thunderbird, or Apple Mail.
Technical Details
When a user sends an email, the client software generates a MIM file with all the necessary information including the names of any attachments, the body text or message, and header details such as sender, recipient, time/date of creation. Generally the MIM files are stored in the temporary message folder of the user's computer. Other related file extensions include: .MSG, .EML, and .PST
.Usability
The MIM files are useful as they allow users to save emails as individual messages which can then be opened and printed from other programs or locations. For example, one could create backups of all their emails by saving each MIM file onto an external drive, or enabling auto-archiving functions within their email client's settings menu.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .MIM) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .MIM extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .MIM file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .MIM extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .MIM extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .MIM file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .MIM file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .MIM file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .MIM file) will be extended to the maximum.
It is also good to check
- if the .MIM file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
