How to open mim files
Piglette's guide on how to use files with a .mim extension

To open mim files with the Winzip software installed, simply double click on the mim file itself in "File Manager" or "Windows Explorer".  This will automatically start up the Winzip program.  Once you have clicked to agree that you will use Winzip only for evaluation purposes (giving you a maximum 28 days in which to try the software for free), the next screen should offer the option of going into Winzip classic mode.  You need to use the classic mode to open your mim files so choose this option.  This will take you to a screen similar to the sample screen shot above.  If you wish, you can then view the individual files one by one by single clicking on a file and clicking the "view" icon.  An even better way is to highlight all the files (as in the screen shot above) by clicking and holding down your mouse button in one corner and dragging your mouse pointer to the opposite corner.  Then click on the "extract" icon and a window will appear asking you to choose somewhere on your computer to extract the component individual files which make up the mim file.  Just choose somewhere to put these files, and Winzip will "extract" the individual files from your mim file, and you can then view the individual files in the normal manner whenever you wish.
