About A1 files

The .a1 file extension is a container used by several disparate software ecosystems, most notably as a saved game state for the classic strategy game Sid Meier's Alpha Centauri and as a legacy drawing file for AlphaCAM CNC software.

For gamers, an .a1 file represents a specific save slot (typically an autosave or turn-based snapshot) containing binary data about map layout, unit positions, and civilization statistics. The primary friction here is proprietary lock-in; these files are unreadable outside the game engine, making it difficult to extract map data or statistics without hex editing. Users looking to "convert" these files are often trying to migrate saves between versions or extract assets.

In an industrial context, the .a1 format functions as a CAD/CAM drawing file associated with AlphaCAM (now part of Hexagon). These files contain 2D geometries or toolpaths for CNC machines. Engineers often struggle with these files because opening them requires an expensive, licensed workstation.

Conversion Best Practices:

For CAD/CAM: To view or edit the geometry without the original software, converting .a1 to standard interchange formats like DXF or DWG is essential for compatibility with AutoCAD or SolidWorks. For archiving or quoting, convert to PDF.
For Gaming: There is no standard conversion target for game saves, but simple file renaming (e.g., to SAV) allows them to be loaded in different slots.
For Developers: If associated with Free Pascal, the file is a static library archive; convert or extract contents using standard archive tools.

Convert.Guru analyzes your A1 file, detects the exact format, and lets you read the text inside.

Users also converted PDF, AI, GMD, GEX, GMK, A2 and A3 files.

The A1 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 A1 converter.
