Cool Edit Pro: What .pk files are and how to turn them off

Once you save a file via Cool Edit, it saves a *.pk file in the save directory as well. This file is used to speed up the loading of a file for the next session. These .pk files can be deleted at any time. They bring no harm to the application or the original file. If you would like to turn them off, from the menu bar, select Options, Settings, System, and uncheck Save Peak Cache files.
