A number of computer applications use FIL - Files List Object File, including ACL (access control list) for windows, dBase, ACG Antivirus, and Cardbox. .fil files contain a list of database objects stored in the database or an associated computer application. Zenworks Desktop Management applications will occasionally use these extensions when they create certain files. The S60 smartphone uses the .fil files to store the Nokia logo pictures. These file types can be opened using any multi-purpose file opener.
