What is an ACSM File?

An ACSM files is a file with the .ACSM file extension, which is an Adobe Content Server Message file. It is the file format used by Adobe Digital Editions to activate and download Adobe DRM (Digital Right Management) protected content. The ACSM files are not eBook files in the regular sense since you cannot open and read the eBooks in ACSM format like eBooks in EPUB or PDF formats. In fact, the ASCM file is the information that communicates with Adobe’s servers to extract the book for users, rather than an eBook saved in the ACSM file.

On the contrary, ACSM files contain data from the Adobe Content Server and are used to authorize that the book had been legally purchased. Then, you can download the real eBook on your computer from Adobe Content Server through the Adobe Digital Editions program. Meanwhile, you can read back the eBooks through the same program on any of your devices. In other words, once your device is properly set up and logged in with the same user ID, you will always have access to your purchased contents within Adobe Digital Editions program. Then, you are able to read the purchased books on any of your devices, without having to repurchase it.

How to open ACSM Files?

To open the ACSM files, you need to install the Adobe Digital Editions on your devices at first. The Adobe Digital Editions app is available on Windows OS, MacOS, Android, and iOS devices. Then, you only need to log in with your Adobe user ID to download and read the purchased Adobe eBooks. You can log in with your Adobe user ID on different devices and you can access to your purchased eBooks on all of these devices. Before you download the eBooks to your device within Adobe Digital Editions program, you need to authorize your computer or mobile device using your Adobe user ID.
