What is a CLL file?

CLL files mostly belong to Callisto.

CLL files store list data used in different communication and catalog applications. They are not a single format but serve several purposes depending on the software that created them.

  • Call Log List: some of CLL files are used to record call details. They may be recognized as a Callisto Clipboard Data file, containing phone call records.
  • Cell Phone List File: some serve as a repository for cell phone contact information. These files are created by the Cell Phone List Creator and sometimes called CaddyList List Files by TapCIS.
  • Catalogue List File: some are used to organize catalog or collection data. These files, produced by ENC Creator, can be XML-based. More details can be found at the related webpage.
  • To view or edit a CLL file, use the software that originally generated it. In cases where the file is in a plain text or XML format, a text editor might display its contents. However, proprietary formats need the designated application to fully interpret the data.

    FilExt.com note: Check the file content with a text or hex editor to assess its format before trying to convert or edit it.
