What is a PKD file?

PKD files mostly belong to Nier: Automata. PKD files are not a universal format but custom container files used in specific systems. One common type is a packed data file seen in video games like Nier: Automata. These files bundle various game assets—such as graphics, audio, and level data—into a single package to help the game load its resources efficiently.
Another variant of the PKD format is used for market research data. In these cases the file acts as a Nielsen data file or a proprietary SPSS file accessible through tools like PKD Reader or PKDTool. This version stores structured statistical information for analysis.
Key details summarized by FilExt.com include:

Custom format: They require the designated software to view or extract their data.

Varied uses: One type holds video game assets; another stores proprietary market and survey data.

Access methods: Use the original game client or specific data viewers to open and inspect the file.

FilExt.com note: Following the native procedure is advised when handling these files to avoid corruption.

How to open a PKD file

You need a suitable software like Nier: Automata to open a PKD file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your PKD file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a PKD file directly in the browser:. Just drag the file onto this browser window and drop it.

PKD file format:

Each file has a definite file format, that is, how the stored data is arranged in the file. The file format can be deduced from the file extension and the signature. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. Knowledge is power - this also applies when dealing with unknown or faulty files. Our examination of the PKD files comes to the following conclusion:

The PKD file extension is not common and includes different formats for different programs. The two most common formats are as follows:

20% of all PKD files start with the magic bytes DKP, which are always the first bytes of this file format. The contents of these files cannot be read by a human; only a computer program can interpret the data. The files are on average 840 KB in size and range from 51 KB to 120 MB. The files contain the following words: DKP. The file name battle.pkd or CharacterSpecList.pkd is typical for these files. Files like these have the following tags: list, spec, character and machine.
10% of all PKD files use the same file format, which have the signature 1F 9D 90 51 AC 40 09 32 64 09 88 83 31. If you open these files in a text editor, you will see only illegible characters. The file size is in the range of 79 KB to 11 MB. Certain words are almost always found in the files, such as 0pIf.

All other PKD files (70%) have no consistent format. Tagged as losk. If you want to find out which format your PKD file belongs to, just click on the button "Choose your .pkd file to analyze".

How to solve problems with PKD files

Associate the PKD file extension with the correct application.
Update your software that should actually open container files. Because only the current version supports the latest PKD file format. Search, therefore, e.g. on the manufacturer website after an available Nier: Automata update.
To make sure that your PKD file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
