The csw file extension is associated with Corel WordPerfect, a word-processing program developed by Corel Corporation. WordPerfect is also included in the Corel WordPerfect Office suite for Microsoft Windows.
A csw file contains setup information used by the installation of Corel WordPerfect. The file supports the software's setup process rather than storing user-created document content.
This is an internal Windows software file, not an interchange format. It should normally remain with the WordPerfect installation and is not intended to be opened or modified as a regular document.
Corel WordPerfect uses csw files internally during setup. Users normally do not open these files directly; leave the file in its original location and use WordPerfect's installer or the installed program to work with the associated software.
A csw file cannot be meaningfully converted to a document or another user-facing format. It contains internal WordPerfect setup information rather than document content.
