What is an .CSK file?
.CSK is Claris Works data
The csk file extension is associated with an old, no longer supported application call Claris Works.
Now you can use a newer version of this program renamed to Apple Works.
This csk 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.
