I cannot find FAT_Filesystem component in CodeWarrior v10.6.3. Could you please press down the Filter button which is at the right-top of ‘Component Library’ View? Please see below.

Is FAT_Filesystem component displaying in the Component list on your side? Could you please attach a screenshot? Thank you very much!
In addition, User can install latest update in CodeWarrior 10.6 from CodeWarrior "Help" Menu->Check for Updates. Or review the link below for how to install update:
