What is a ACSM file
Files with an ACSM extension are closely related to Adobe Digital Editions. This product licensed by Adobe manages and reads eBook files as well as other file types for digital publications. However, ACSM files do not contain the eBook data itself. Instead, the information found in ACSM files is used to download, activate, and authorize the reading of eBook files.
Adobe's Content Server sends the ACSM files directly to Adobe Digital Edition where they can be opened. When using another eBook reader, ACSM files may appear as well. This means that, before being able to correctly transfer the eBook to the device, Digital Editions has to be installed. Usually, ACSM files do not occur when downloading an eBook. If they appear on the computer however, it means that the download has been interrupted. It can be resumed by simply double-clicking on the ACSM file.
Here's a small, but not exhaustive list of programs that can open ACSM documents:
