.CA3 File

The ca3 file extension is mainly related to an audio output format recorded using the Casio WK-1800 Keyboard.

It was a type of 76-key portable keyboard with Floppy Disk Drive for song play and storage released around 2003.

These ca3 files contain data produced with the use of "save all" command.

This ca3 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:

These files can probably only work in Casio WK-1800.

How to convert:

As far as we know, this .ca3 file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
