Some FRZ files are also SNES ROM save files, which store a game’s state. These save files are compressed using GZIP and work with emulators. For example, you can open these with Snes9x.

FRZ file format:

If you know the file format, you can also find out how to open or edit the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. 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. If there are problems opening a file, you must first determine the file format used. Below is our analysis of the FRZ files:
