Sony PlayStation Game Save Format | Sony | Game Files |
The PSX file extension is associated most commonly with saves from the PlayStation gaming console, developed and published by Sony Interactive Entertainment. PSX files are used to store information in memory, like progress in a game, points achieved, etc. It is typically a generic binary format that is specific to the program used to create the file. They are simply named according to the game that they are created by, for instance FF7 files are save files from the game Final Fantasy VII.
The PlayStation platform stored its save files differently than other gaming platforms of its era. Memory cards or CD space were used to store PSX type save files, and you typically had to purchase each game separately. This format could also be transferred to other systems, like the PlayStation 2, with the help of compatible software.
Technical Details
The PSX file extension could be stored in various formats, but most commonly it is usually found in either the Generic Binary format or Big Endian Binary format. It is encoded in UTF-16 encoding with text containing a minor form of encryption, depending on the platform the binary file was created on. It visually appears as mostly nonsensical numbers and symbols.

Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .PSX) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .PSX extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .PSX file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .PSX extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .PSX extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .PSX file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .PSX file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .PSX file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .PSX file) will be extended to the maximum.
It is also good to check
- if the .PSX file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
