Olympus Master Monitor – MEDIALOCK.EXE
Mmonitor.exe installs with the Olympus Master or Olympus Master 2 software for your Olympus digital camera. You may find the file in your C:\Program Files\Olympus\Olympus Master or \Olympus Master 2 folder. Olympus Master is designed to help you organize, edit, and share your images and movies. You'll find more information at http://www.olympusamerica.com/cpg_section/oima_softwareMaster.asp.
If you let mmonitor.exe run on system startup, it'll sit in memory looking for your camera. As soon as the camera is connected, it will launch the Olympus Master program. If you don't mind running the program yourself from Start > Programs, you can get by without this file.
Safe
