.PKG_ File Extension

The pkg_ file extension is related with Apple Newton platform. The Newton platform was an early personal digital assistant hardware/software platform developed by Apple Computer (now Apple Inc.).

Development was started in 1989 and officially ended on February 27, 1998. Some electronic engineering and the manufacture of Apple's Newton devices was done in Japan by the Sharp Corporation.

Most Newton devices were based on the ARM 610 RISC processor and all featured handwriting recognition software. Most Newton devices were developed and marketed by Apple, but other companies, notably Sharp, Motorola, and Digital Ocean, also released devices that ran the Newton OS. None were as successful as Apple's devices.

PKG_ file extension was an uncommon file extension for Apple Newton package, common file extension was PKG and now Apple is using the PKG file extension for MAC OS X (macOS) installation packages.

.PKG_ file format is deprecated and this file format is no longer supported.

Currently, .PKG_ file type is not actively used and is obsolete. This usually happens with system files in older operating systems, files from long-discontinued software, or with previous versions of some file types (documents, projects, images, etc.) that were replaced in later versions of the original programs.

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 .pkg_ 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.
