Opening CWK files

Did your computer fail to open a CWK file? We explain what CWK files are and recommend software that we know can open or convert your CWK files.

What is a CWK file?

Files that contain the .cwk file extension are most commonly associated with the ClarisWorks or AppleWorks productivity suite that is used for Apple computers. The CWK files may contain word processing documents, drawings, presentations or spreadsheets that have been created by these software programs. Claris was bought out by Apple in 1998.

The .cwk file extension is also used by the CattleMax software program. This program uses the .cwk file suffix for data files that are referenced by the program.

The CGPrevue program also uses the .cwk file extension. These CWK files contain work files that are created using the CGPrevue program.
