What is a CWZ file?

CWZ files mostly belong to CircuitWizard/Designspark PCB. CWZ files primarily serve as Circuit Wizard design files used in circuit schematic and PCB layout work.
This file format stores detailed circuit design data including schematics, component connections, simulation settings, and layout configurations. It is created by design software such as CircuitWizard or Designspark PCB.
Other specific uses include:
  • Crash dump file: Employed by Cisco WebEx, this version captures system errors for diagnostic purposes.
  • Working papers data file: Used by CaseWare Working Papers, this variant holds project data for financial and audit documentation.
  • FilExt.com notes: For design files, the original circuit design software ensures proper viewing and editing. For diagnostic or financial files, using the intended application is advised. More details are available at this resource.
