No manner of installing an OS will erase any files.

However, you have two options with an new OS installation.


1) A simple install "upgrades" your system, by replacing any part of the OS that is new and leaves many older files (especially any 3rd party extensions and add-ons) installed where they were originally placed. Some applications that are unable to run may be placed into a special folder. The risk here is that the older stuff may keep the new OS from performing properly or as efficiently as designed. It would be up to you to find those things and update or weed out what seems to be hurting performance.


2) A clean install will wholly replace your old OS installation and everything will be completely and safely working the way Apple designed the OS to operate. The old OS will be stored away into another folder called something like "Previous Operating System." The downside here is that you will probably lose many of your previous settings you liked (like your desktop pictures, etc., anything you customized over the use of your iMac) and you will have to reset those things. And you will have to reinstall every non-Apple application, printer and/or scanner drivers, etc. that you desire to use with your iMac. One advantage may be that you can see if the new OS performs for you well, and then as you install new non-Apple stuff, if anything starts to go wonky, you will have a good clue what might be the culprit.


Hope this helps.
