what is acsm file

If you purchase books from Google Play Store, it is common to see .acsm file. But what is .acsm file? How to open it? There must be many questions over your mind. This article will help you get these questions answered completely.

What is .acsm file?

.acsm file is not a real file but a download link for the eBook you purchased or rented that distributed by Adobe Content Server. It obtains the data from the Adobe Content Server to activate and download the original content of the eBooks, such as ePub and PDF eBooks.

It acts like a connection between Adobe Content server and the book authorized Adobe Digital Editions ID which means if you use the same Adobe ID on different computers, you are able to download and open the same DRM-protected .acsm file with the Adobe Digital Editions. That is one of many reasons that so many eBook vendors employ this eBook distribution method because they think this can give seamless fulfillment of books across devices.

I think the most important reason that the eBook vendors use the Adobe Content server to distribute their eBook contents to their customers is that it can add DRM protection to the eBooks.
