What is a .0ADSAVE file?
A .0ADSAVE file is a type of file that is used to save your progress in a video game called 0 A.D., which is made by Wildfire Games. This game lets you experience ancient warfare in real-time strategy format. When you save your game in 0 A.D., it creates a .0ADSAVE file. This file is like a container that holds all the details about how far you've gotten in the game. It's a bit like a box where you keep all the pieces of a board game so you can set it up quickly the next time you want to play.
Inside this "box," or .0ADSAVE file, there are two important pieces: a metadata.json file and a simulation.dat file. These files are like the instructions and pieces of the board game. They tell the game everything from where your soldiers are, what technologies you've discovered, to how much of the map you've explored. The .0ADSAVE file is compressed, which means it's been squished down to take up less space, kind of like when you pack a suitcase and push down on it to zip it up. Because it's compressed, you can actually open it up and look inside, just like you can unzip a suitcase. To do this, you would change the name of the .0adsave part to .zip and then use a program that can open zip files. Windows has a program called File Explorer, and macOS has something called Archive Utility that can do this. Once you "unzip" the .0ADSAVE file, you'll see a folder with the same name as the file, and inside, you'll find the metadata.json and simulation.dat files.
But, if you're just playing the game, you don't need to worry about unzipping these files. The game 0 A.D. itself knows how to read the .0ADSAVE file and load your game progress from where you left off. So, when you want to continue your ancient warfare adventures, you just need to open 0 A.D., and it will handle the .0ADSAVE file for you.
