What is a CWB file?

CWB files mostly belong to Huawei IdeaHub.

This file extension is used in different contexts. The most common form is the Huawei IdeaHub whiteboard file. These files store interactive session data, including drawings and handwritten notes, captured on Huawei IdeaHub devices.

Other notable uses include:

• Cakewalk audio file
  This version of a CWB file uses the RIFF structure to bundle audio project data. It is associated with Cakewalk Sonar. For more details, visit Cakewalk by BandLab.
• Corel WordPerfect Backup
  This variant is a backup file for WordPerfect documents. It is intended for restoring previous versions of work. More information can be found on this webpage.

This file is not a simple text document. It is a specialized project file that holds session or backup data depending on its origin. Its internal structure varies with each purpose, and developers sometimes embed additional metadata that users rarely see.

FilExt.com note: To open a CWB file, check its source. Use Huawei IdeaHub software for whiteboard sessions, Cakewalk Sonar (or compatible audio editors) for audio projects, and Corel WordPerfect for backup files.
