Downloading Alice worlds

Most likely your computer does not know what an Alice world file is, with extention .a2w. If the Alice world you download is called story.a2w, your computer may think it is a .zip file and rename it to or

DO NOT unpack it or extract files, but instead rename it back to story.a2w.

If you can't figure out how to rename it, you don't have to. Instead when you are loading the file into Alice, you can load it in as a .zip file if you select the option to load "ALL FILES", and not just ".a2w files".

If you have trouble downloading an Alice world, sometimes I will put up a .zip folder with the Alice world inside. A .zip file is a compressed file that uses less space. If you download this, then you will need to unpack the .zip file. The Alice world cannot run if it is compressed. Then you can try to load the .a2w file. It should have the correct name in this case.
Sometimes with .zip folders you can look at files inside them so you don't realize that they have not been unpacked. But you do need to unzip the folder before using the Alice world.

Also remember that you cannot click on the .a2w file to get it to run. You must start Alice, then File, open file and load the file into Alice.
