What is a PUF file?

PUF files mostly belong to Paradox InField Update Utility.

An PUF file does not refer to a single type of file. It may serve different purposes depending on its origin.
For example, one common use is as a Paradox device firmware update file. In this case the file carries the firmware needed to update alarm system devices, and it is managed by the Paradox InField Update Utility. More details can be found on the Paradox website.
Another example is a Crestron firmware update file. These PUF files often use a ZIP archive structure to package the firmware update data used by Crestron Toolbox, and they can also serve as a Polycom firmware package via Crestron Studio. Additional information is available at the Crestron site.
Other variants of the PUF extension include:

Tax return data files / Public Use Files: These contain tax information or statistical data, and are used by applications like TAX-RATER or via tools such as PUF2BIN. More details are on the IRS website.
PLAXIS user preference files: These store configuration settings for the PLAXIS software, maintaining user preferences. See more at the PLAXIS page.
Compressed Pro Tools files: Labeled as Programmable Universal Files, these hold compressed audio data used in Pro Tools environments.

To open or view a PUF file, use the specific utility provided by the device or software manufacturer. For firmware updates, do not open the file with a generic editor; instead, update the device using its trusted update tool. Similarly, tax data files or user preference files should be handled with the corresponding application.
FilExt.com tip: Understanding the source and intended use of your PUF file is key to processing it properly.

PUF file format details:

Each file has a definite file format, that is, how the stored data is arranged in the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the PUF files looks like this:
