What is a CB file

CB files mostly belong to Reckon Accounts Business.

The CB file extension is used by different software systems. A single extension may refer to cashbook data files, CAD project files, database records, codebooks, design files, or even game and archive files. How the file is opened depends on which internal format it uses.

Usage examples:

  • Cashbook Data: Files using the JetDB format store accounting records. These files are used by Reckon Accounts Business. See more details at Reckon Accounts Business.
  • CAD Projects: Some CB files are written in XML and act as project files for CAD software like CamBam. More information can be found at CamBam.
  • Database and Codebooks: A portion of these files contains database records. They can follow formats such as CAP used by systems like JewelSuite or even use structures similar to Clarion Database Files.
  • Design and Archive Files: Other CB files include design data for embroidery, PCB layouts, or even compressed game save data and comic archives.

How to Open and View:
If you have a CB file, first check for clues in the file’s header. A text editor may reveal XML tags or database headers that indicate its type. Use the specific application (for example, Reckon Accounts Business for accounting files or CamBam for CAD files) to properly open and view your file.
FilExt.com tip: It is wise to back up your file before trying to modify it.

Knowledge is power - this also applies when dealing with unknown or faulty files. Our examination of the CB files comes to the following conclusion:
