Well, this can be either a FileWrangler Archive, a Zone Alarm Pro Data File, or a Software Installation Settings file.. . It is most likely the FileWrangler Archive.. The Archive needs to be opened by a program called CursorArts FileWrangler. Download it here (You can get a 30-day free trial):

If it's a Software Installation Settings file, it most likely contains instructions for installing a Windows program. Open this with a text editor such as notepad (click/double-click, choose Select Program from a list, choose notepad and click OK - for Windows XP).
