What is a GZF file?

GZF files mostly belong to Ghidra. GZF files are used as project files by the Ghidra reverse engineering tool. They serve to store all project data, including analysis results, user settings, and binary information.
These files are based on Java and use GZIP compression to keep data size small and loading times efficient.
Key Details compiled by FilExt.com:

• Project file: Contains comprehensive data from your reverse engineering work.
• Compressed: Uses GZIP to reduce storage space and speed up file access.
• Java-based: Built on a platform that assures portability and secure operations.

If you have a GZF file, you should open it with Ghidra. For more information, visit the Ghidra SRE webpage.
FilExt.com tip: Few users know that the compression aspect of these files not only saves disk space but enhances project loading speed, making the analysis process smoother.

How do you open GZF files?

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

GZF file format:

To view or edit GZF files you need to know the file format, because it determines how the data in this file is stored. The file format can be determined based on the file extension and the signature (the first few characters of a file). However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So you need a detailed analysis of a file to find out the format and the associated program. Below you will find our evaluation of the GZF files:

The GZF file extension is rarely used and mainly uses a defined GZF format. However, the following two file formats are common:

• 96% of all GZF files save the data in Java file format. This format is used to save Java objects to a file (ex. save game state as file) via object serialization. Such a Java object may contain functions and data like settings, images or videos. These are binary files, so they do not contain words or text. A typical file size is 350 KB. The file type was created recently. The keywords Program and FOLDER_ITEM are typical for these files. A usual file name is s1mple.gzf or PvZ_reversed.exe.gzf. Such files sometimes refer to mple, reversed, crackme and patched.

All the rest of the GZF files (4%) have different formats. If you want to find out which format your GZF file belongs to, just click on the button "Choose your .gzf file to analyze".
