This page provides an explanation of what ACSM files are as well as guidance on how to access them to make it possible to download certain eBooks, which need the utilization of ACSM files. Certain eBooks can only be downloaded if ACSM files are present. Some eBooks are only available for download in the form of ACSM files.
What Is an ACSM File?
A file containing an Adobe Content Server Message file has the file extension ACSM. To activate and download Adobe DRM-protected content, utilize Adobe Digital Editions.
As they cannot be opened and read like other eBook formats like EPUB or PDF, ACSM files are not technically eBook files in the traditional sense. Actually, the ACSM file itself is nothing more than data used to connect to Adobe’s servers. The ACSM file does not include an eBook, nor is it possible to extract the book from the file.
The true eBook file may be downloaded to your computer using the Adobe Digital Editions program, and then read back using the same software on any of your devices. In contrast, ACSM files contain data from the Adobe Content Server that is used to verify that the book has been lawfully acquired.
To put it another way, after correctly configuring your device, you may open an ACSM file to register a book to the user ID you’ve used to set up Adobe Digital Editions, and then read the book on any device that is running ADE with the same user ID without having to buy it. Further details about that procedure are provided below.

How to Open ACSM Files
To open ACSM files on Windows, macOS, Android, and iOS devices, download Adobe Digital Editions. The same book may be downloaded on any other device that uses Adobe Digital Editions with the same user ID after being downloaded on one device.
Note: During the ADE setup, you can be prompted to install Norton Security Scan or another irrelevant product. If you want not to, you can.
To link your eBook vendor account with Adobe Digital Editions, select Help > Authorize Computer from the menu. This process ensures that your books are provisioned for your other devices, that they may be downloaded again in the event that your gadget malfunctions or the book are erased, and that you won’t have to pay for the book again for your other devices.
With the account, you specified on the authorization page, read material that has been DRM-protected by Adobe.
Note: By selecting the relevant option on the Authorize Your Computer page, you may also approve the computer without providing an ID.
How to Convert an ACSM File
An ACSM file cannot be converted into another eBook format, such as PDF, EPUB, etc. since it is not an eBook. The ACSM file is really a straightforward text document that provides instructions on how to get the actual eBook, which may in reality be a PDF, etc.
Note: Right-click the book in Adobe Digital Editions and select Show File in Explorer to locate the book that ADE downloaded using the ACSM file. This is most likely located in the C:Users[username]DocumentsMy Digital Editions folder on Windows.
Still Can’t Open Your File?
If your ACSM file won’t open because it’s a little different from other file formats, look into the issues you find. When you access the eBook, if an authentication issue appears, it’s likely that either ADE isn’t installed or you’re not logged in with the same ID that bought the book.
But, double-check the file extension to make sure it genuinely says “ACSM” if you’ve followed the preceding advice and your file still won’t open. Certain file formats have a file extension that looks a lot like ACSM, but they’re actually distinct and need other software.
