.OCA File

The oca file extension is associated with Visual Basic, by Microsoft Corporation. For every custom control file (.OCX) that Visual Basic uses, there is an accompanying .OCA file of the same file name. For example, GRAPH16.OCX has an accompanying .OCA file called GRAPH16.OCA. An .OCA file is a binary file that functions as both an extended type library file and a cache for the custom control file.

Files with oca extension are used for Microsoft Visual Basic. It is a binary file format.

How to open:

This file type is not meant to be opened directly, there is no software that could open and work with it directly, or there is no information available in public sources about opening this file type. This is usually the case of some internal data files, caches, temporary files etc.

How to convert:

As far as we know, this .oca 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.
