The Cache Killer Pro Prefs file, located in the Preferences folder, is a plain text file that can be edited with an application such as SimpleText, BBEdit, or Microsoft Word.

The first line of the file is a number that indicates the number of cache folders to manage.

The next series of lines specify the full paths of each cache folder. The number of paths listed must correspond to the number in line one. For example, if line one is "3" then lines two, three, and four should list the full paths of the cache folders that will be managed.

The last line is a number that indicates the Delete Interval, or the number of days between deletions.
