KEY file extension - OS/2 archive key

What is key file? How to open key files?

File type specification:

Archive and compressed file type icon Archive and compressed file type

The key file extension is associated with OS/2, an operating system for IBM-PC compatible computers. The .key file stores archive key.

The IBM OS/2 operating system was discontinued and replaced by eComStation (eCS).

This key 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.

OS/2 is operating system developed by IBM for personal computers. OS/2 is no longer marketed by IBM and support for OS/2 was discontinued in 2006. OS/2 is very similar like Windows in many ways, but also has similarities with Unix. The last version of OS/2 is named OS/2 Warp.

Help 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 .key 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.
