.CH File

The ch file extension is associated with the IBM OS/2, an operating system for IBM-PC compatible computers developed by Microsoft and IBM, later only by IBM.

The ch file stores configuration data for OS/2.

This ch 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.

How to open:

When placed in proper folder, the OS will load the configuration data automatically.

How to convert:

Configuration files cannot be typically converted to anything else.
