What is a .ACSM file?
The file extension .ACSM stands for Adobe Content Server Message. This type of file is not an eBook itself, but rather a small file that helps manage the download of eBooks. When you purchase an eBook online, you might receive an .ACSM file instead of the actual eBook. This file contains information necessary to securely and legally download the eBook from the internet.
To use an .ACSM file, you need a specific program called Adobe Digital Editions. This program is designed to read and manage digital publications, including eBooks. When you open an .ACSM file with Adobe Digital Editions, the program reads the information in the file, connects to the Adobe Content Server, and then downloads your purchased eBook to your computer or device. After the download is complete, you can read your eBook directly through Adobe Digital Editions.
Adobe Digital Editions is available for all major platforms, including Windows and macOS. To open an .ACSM file, simply install Adobe Digital Editions, and then double-click on the .ACSM file. The program will take care of the rest, ensuring that your eBook is downloaded and ready for you to read.
