What is a QPF file?
A .QPF file is most commonly a Quartus II Project File created by software from Altera, which is now part of Intel. These files contain the project settings, component lists, and configuration data needed to develop hardware for Field-Programmable Gate Arrays (FPGAs).
However, the .QPF extension is shared by other specialized software. It can also be an Instrument Protocol Definition file used by QIAGEN laboratory equipment, such as the QIAcube Connect. In the manufacturing sector, a .QPF file might be a Metrology Part Program used by OGP ZONE3 Software or Hexagon PC-DMIS. These metrology files are often ZIP archives stored under the .QPF extension. Additionally, it might serve as a Quest3D project or a QuickPad encrypted document.
How to open QPF files?
To open a Quartus II Project File, you must use Intel Quartus Prime. Because these FPGA files are often stored as plain text, you can also view their basic contents using a code editor like Notepad++ or Visual Studio Code.
If the file comes from a laboratory environment, you must open it with the corresponding QIAGEN instrument software. If the file is a Metrology Part Program, you can open it with ZONE3 or rename the extension to .zip to extract the internal contents using tools like 7-Zip.
Inspect your file online
Because .QPF has multiple possible meanings, it is easy to experience software compatibility problems. viewer.online/qpf can analyze .QPF files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available.
Summary
If you do not know the origin of your file, we recommend using viewer.online/qpf to identify the actual format of the user's file. This service is highly useful for identifying, inspecting, and understanding .QPF files without installing software or dealing with compatibility problems.
