About UPP files

The .upp extension is a dual-purpose format primarily associated with Unity game development and UP! 3D printing workflows.

1. Unity Player Preferences (Primary Use)

In the context of the Unity engine, a .upp file often represents an exported or serialized version of PlayerPrefs - the system used to store user save data, configuration settings, and game state (e.g., volume levels, unlocked levels, high scores) between sessions. While Unity typically stores these in the system registry (Windows) or plist files (macOS), developers and third-party tools use the .upp format to package these settings for transfer, debugging, or backup.

Common Friction Points:

Unreadable Data: These files are often binary or proprietary text formats, making them impossible to edit with a standard text editor like Notepad.
Platform Lock-in: Moving save states between different OS versions of the same game is difficult without converting the data to a neutral format.

Best Conversion Targets:

For Editing/Cheating: Convert to JSON or XML. This allows gamers and developers to modify values (like currency or health) in a human-readable structure before re-importing.
For Archiving: Convert to TXT to keep a readable log of the settings.

2. UP! 3D Printer Project

Less commonly, .upp files are legacy project files for UP Studio, the proprietary slicing software for Tiertime's UP! series of 3D printers. These files contain the 3D model geometry along with slice parameters (layer height, infill, support structures) specific to UP! printers.

Common Friction Points:

Proprietary Obsolescence: Modern UP! printers and software have largely moved to newer formats like .UP3 or TSK, leaving older .upp files difficult to open.
Compatibility: You cannot open a .upp file directly in popular slicers like UltiMaker Cura or PrusaSlicer.
Confusion: Users often confuse this with Ultimaker's .UFP format due to the similar acronyms.

Best Conversion Targets:

For Printing: Convert to generic STL or OBJ to reclaim the 3D geometry for use in modern slicers.
For Machine Control: Convert to G-Code if you need to run the file on a non-UP! printer (though this requires re-slicing).

Convert.Guru analyzes your UPP file, detects the exact format, and lets you read the text inside.

Users also converted XML, JPG, VALUES, RESS and SCENE files.

The UPP Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our UPP converter.
