What is an ACSM file?

ACSM files mostly belong to Digital Editions by Adobe. An ACSM file is a license file that Digital Editions e-book manager uses to download and activate e-books and audiobooks. This file is commonly called an Adobe Content Server Message. It contains text data written in XML and used to verify whether a user is legally allowed to download and read a DRM-protected e-book (EPUB or PDF) they have previously purchased or borrowed. Adobe Digital Editions usually handles ACSM files behind the scenes. If you have encountered this file, it's likely the download was interrupted or Digital Editions may not be correctly installed/authorized to automatically open such files.

How can I open an ACSM file?

You need a suitable software like Digital Editions from Adobe to open an ACSM file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your ACSM file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a ACSM file directly in the browser:.
