File extension cwk is mainly known for its use in Apple ClarisWorks, a now discontinued office suite, formerly developed by Apple.

The cwk file may contain word processing document, spreadsheet, presentation or even drawing.

If you own old ClarisWorks files, but not ClarisWorks, your best bet is to open the documents in a text editor and copy past your texts out to another word processor. It is because no current word processors support this file format.

This cwk file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.
