COREX, or CORpus EXploitation, is corpus-analysis software for Microsoft Windows. Its plk files support the processing and annotation of text.
The files contain part-of-speech tagging, lemmatisation, lexicon link-up and indications of multi-word structures. They are part of the data used by COREX.
COREX appears to be obsolete, and the plk format is marked obsolete.
Open the file with COREX on Microsoft Windows, if the software is available. COREX is required to interpret the file's linguistic annotations correctly.
Because the contents are stored in text format, a plain-text editor can display them, but it may not show the annotations in the way COREX does.

The plk file extension is associated with ATI Radeon graphics cards. The Radeon product line was developed by ATI, which was later acquired by AMD.
A plk file contains part of the video driver used to support an ATI Radeon graphics card. It is a legacy system file rather than a document intended for direct use, and the format is probably obsolete.
A plk file is intended to be used by the ATI Radeon video driver, not opened manually. The appropriate driver software loads it as needed on a system with compatible Radeon hardware.
There is normally no general-purpose application for viewing or editing this file.
A plk file cannot be meaningfully converted to another format. It is a component of a legacy video driver, so it should be retained with the driver or removed only when the associated driver is uninstalled.
