ACSM (Adobe Content Server Message) files are not actual eBooks, but they are documents used to authorize and download eBooks from Adobe Digital Editions. When an ACSM file is opened in ADE, it connects to Adobe's servers to verify your purchase and downloads the real eBook later. This system is particularly helpful in protecting copyright content using Adobe's Digital Right Management technology while ensuring only authorized users can access the content.

Besides this, it allows you to organize and edit your eBooks more freely, improving your overall reading experience.
