What is a 0ADSAVE File Type?
Only if you play the game 0 after JC will you probably encounter a 0ADSAVE file. This file is created when you register your game and is intended to be loaded by 0 A.D. The 0ADSAVE files contain a variety of game data, including information on civilizations, soldiers, combat experiments, research technologies and explored terrain.
Since the 0ADSAVE file is compressed Zip @-@, you can extract the contents at l' aide d' a Zip- decompression utility. To do this, change the extension of the .0adsave file to .zip, and then decompress-on it with a Zip utility, such as Microsoft File Explorer, which comes with Windows, or Apple Archive Utility, which comes with MacOS.
