HP OmniGo GEOS compressed file archive
File type: Archive and compressed file
A gpk file extension identifies a compressed archive used by the GEOS operating system on HP OmniGo organizers.
A gpk file can contain files used by the GEOS software and the organizer.

Record marked as obsolete and not updated for a long time.
The gpk file extension is associated with the HP OmniGo 100 and 120 personal organizers, produced by Hewlett-Packard in 1995. These devices used GEOS and an Intel 80186-class processor.
GPK files are compressed archives that form part of the GEOS software environment. They can hold files needed by the operating system or by software installed on the organizer.
Open a gpk file in the GEOS environment on a compatible HP OmniGo organizer. The original GEOS software is required to use the archive as intended.
Modern archive utilities generally do not support this obsolete format, so a file copied to a current computer may not open directly.
If the archive can be accessed on a compatible HP OmniGo organizer, extract its contents there and transfer the individual files to another system.

GEOPAK was developed by Bentley Systems as a suite of civil engineering and design software. Its coordinate geometry tools use gpk files as project databases.
A gpk file contains coordinate geometry elements used by a GEOPAK project, including data created and managed during civil design work. It is a working database for the software rather than a general-purpose database format.
The format is intended to be used with GEOPAK on Microsoft Windows. The file should normally remain with the other data belonging to its GEOPAK project.
Open the file with GEOPAK Civil Engineering Suite on Microsoft Windows. GEOPAK may need the associated project files to use the database correctly.
GEOPAK coordinate geometry database files are not generally convertible to another database format. GEOPAK's coordinate geometry export or reporting features, when available, can be used to extract required project data into a supported interchange format.

The gpk file extension is also used for one of the files in WaveLab, an audio editing and mastering suite, developed by Steinberg Media Technologies GmbH.
The GPK format is used for audio peak files. Peak files are small files, which are automatically created by WaveLab each time a file is modified or opened by the application.
Peak files contain information about the waveform, and determine how it is drawn in the wave window.
You can work with *.gpk files in Steinberg WaveLab.
Probably cannot be converted to other formats.
