What is a QPF file?
A file with .qpf extension is a text file created with QuickPad software which is a free application offered by Klumbu, as the evolved version of Notepad for Windows Operating System. QPF files can only be opened and viewed in QuickPad and provide a bare minimum security of sensitive data this way. The text inside the document is not encrypted using any password. Instead, it is encoded by the software to make it somewhat secure.
QPF File Format
QPF files are text files that are created and saved in human readable form. The only difference is that to read these files, these need to be opened in QuickPad. QuickPad offers features such as Word Wrap, text formatting, auto save, focus mode, and more. In addition, text can be imported from INI as well as TXT file format.

FAQ
Q1: What happens if I delete my QPF file?
A: While your source code files are safe, you will lose your project structure and settings, forcing you to create a new project and re-add all files and configurations manually.
Q2: Can I edit a QPF file manually in a text editor?
A: No, QBL files are not natively compatible with QuickBooks for Windows; you must use a compatible version of QuickBooks for Mac to restore it.
Q3: What is the difference between a QPF and a QSF file?
A: The QPF file is the main project container that lists source files and top-level settings, while the QSF (Quartus Settings File) contains detailed pin assignments and timing constraints.
Q4: Is the QPF file used for simulation?
A: No, the QPF file is for the Quartus Prime synthesis and implementation toolflow; simulation tools like ModelSim typically use their own project files (.mpf).
Q5: Can I have multiple QPF files in one directory?
A: Yes, a single directory can contain multiple QPF files, each representing a different project or a different revision of the same project.
