About .uss Files
USS files are binary data files that save the current state of a running UAE emulator session.
They are known as UAE Saved State files and use the MIME type application/octet-stream because they store raw binary data.
- Main use: They capture the complete status of an emulator, including memory, registers, and disk information, so you can resume your session exactly where you left off.
- File type: As a binary file, it does not contain plain text. It’s designed to be read by the emulator, not manually edited.
- Usage: Primarily used by the UAE emulator (such as WinUAE) to save and restore gameplay or application states.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a .uss file?
A .uss file is a UAE Saved State file used by Amiga emulators like WinUAE. It stores a snapshot of the emulator's current memory, CPU registers, and hardware state, allowing users to pause and resume their emulation session exactly where they left off.
How do I open a .uss file?
You cannot open a .uss file by double-clicking it. Instead, launch your emulator (e.g., WinUAE or FS-UAE), navigate to the Miscellaneous or Savestates menu, and select the option to Load State. Browse to the location of your .uss file to restore the session.
Can I edit a .uss file with a text editor?
No, you should not edit .uss files with text editors like Notepad. These files contain raw binary data formatted as application/octet-stream, and modifying them manually will corrupt the saved state, rendering it unreadable by the emulator.
Which programs create .uss files?
The primary software associated with this extension is the Universal Amiga Emulator (UAE) family. This includes WinUAE for Windows and FS-UAE for multiple platforms (Windows, macOS, Linux). These programs generate the file when a user triggers the 'Save State' command.
Why does my .uss file fail to load in WinUAE?
Loading errors often occur if the emulator configuration has changed since the state was saved. Ensure you are using the same Kickstart ROM, RAM settings, and hardware configuration (e.g., CPU model, Chipset) that were active when the .uss file was created.
What is the MIME type for .uss files?
Because .uss files are proprietary memory dumps, they do not have a specific registered media type. They are generally classified as application/octet-stream by web servers and operating systems due to their binary nature. You can learn more about this generic type at mime-type.com.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
