What is an ACSM file?
Developed by Adobe Systems, the ACSM is one of the default file formats of the Adobe Digital Editions, an eBook and other publications hub. The Adobe Content Server Message extension stores a message file sent by the Adobe Content Server. These files contain the key to activate and link to download the eBook but don’t hold the book itself.
It is a digital encryption technology that allows users to download and read digital books and other publications legally. It is unusual for the end readers to come across an ACSM file, but if they do it can be because the download was incomplete.
