The ACSM file format is used by Adobe Digital Editions for digital rights management of its ebooks. You need to use the Digital Editions software to load any ebook that uses the ACSM files in conjunction with the ebook file. The ebook is loaded on to the Nook through Digital Editions, and the ACSM file is checked to make sure that the book is a legitimate copy and is eligible to be loaded on to the Nook.
