You need to install Adobe Digital Editions and register an account. Then, when you click on that file it'll download the epub to Digital Editions's Library. Then you can further process it if you like.
@Andre Louis .acsm is kind of a link that enables you to download the protected epub file by using Adobe Digital Editions app on windows computer. For other platforms there are more supported apps but Adobe Digital Editions is the reference I guess.
