Windows — Recommended: 7-Zip (Free)

1. Install 7-Zip — Download from the official site and install.
2. Put parts together — Ensure Terrain_Library_Full.zip, Terrain_Library_Full.z01, and Terrain_Library_Full.z02 are in the same folder (don’t rename them).
3. Extract via 7-Zip — Right-click Terrain_Library_Full.zip → 7-Zip → Extract Here (or Extract to "Terrain_Library_Full\").
4. Let 7-Zip combine parts — It will automatically read .z01 (and any .z02, .z03, etc.).

Mac

1. Put parts together — Place all three files in the same folder.
2. Use The Unarchiver — Install (free), open it, and set it to handle ZIP files.
3. Extract — Double-click Terrain_Library_Full.zip; it should automatically combine all parts and extract.

Quick Troubleshooting

• Start from Terrain_Library_Full.zip, not .z01.
• “Unexpected end of archive” → A part is missing or incomplete; re-download.
• Don’t rename parts; filenames must match exactly across all pieces.
• If password-protected, confirm the exact password (watch for extra spaces).
