What is a QPF file?

QPF files mostly belong to Quartus Prime. The QPF extension is not tied to a single function; it is used for project and protocol files in different fields.
Quartus Prime Project File: This type holds FPGA design data including configurations and setup information. It is meant for hardware design and simulation in a developer environment.
QIAquick PCR Cleanup Protocol File: This version carries standardized instructions for PCR cleanup. It is used with lab automation systems such as QIAcube Connect. More details are available at QIAGEN QIAcube Connect.
Coordinate Measuring Machine Project File: This file contains measurement and project data for quality control or manufacturing processes. Often employing ZIP compression, it is managed by software like PC-DMIS, and is related to tools such as Carl Zeiss Q-DAS and GOM Inspect. For more information, see Hexagon Manufacturing Intelligence.
FilExt.com tip: To view a QPF file, use the original software that generated it.

How do you open QPF files?

You need a suitable software like Quartus Prime to open a QPF 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 QPF file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a QPF file directly in the browser:. Just drag the file onto this browser window and drop it.

QPF file format details:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. If the file extension does not match the file format, double-clicking on the file will cause an error upon opening. So a detailed analysis of a file is vital in order to determine the format and the associated program. Below you will find our evaluation of the QPF files:

QPF is rarely used as a file extension and covers different formats for different programs. However, the following two file formats are common:

55% of all QPF files use the popular config file format. A configuration file is used by computer software to store settings. It consists of a text-based content with a structure and syntax comprising key–value pairs for properties, and sections that organize the properties. These files are text files, so they contain words and text. A typical file size is 1 KB. It is a modern file type. The files contain the following words: -------------------------------------------------------------------------- , # Your use of Altera Corporation's design tools, logic functions, # Copyright (C) 1991-2013 Altera Corporation, # Your use of Intel Corporation's design tools, logic and Intel Corporation. All rights reserved. Examples of file names are Lab2.qpf. Such QPF files store data about assignment.
30% of all QPF files start with the bytes QEF crucial for this file format. These files are binary files, so they do not contain text, but only cryptic characters. Most of these files are 48 KB to 81 KB in size. The file name DNA_QIAampDNABloodMini_BloodOrBodyFluid_ElutionVolume100_V3.qpf is typical for these files. Such files are related to mini, standard, fluid, blood, qiaampdnablood, orbody, qiaamp, rneasy and volume.

The remaining 15% of all QPF files are different files with different signatures. The category is elution, animal, ffpetissue, sections, cleanup, tissues, dneasy, cells or soil. If you want to find out what your QPF file contains, drag and drop it onto this page.

How to solve problems with QPF files

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