Reading protected eBooks on desktop or laptop. Transferring eBooks to your device via Adobe Digital Editions

We assume that you already have ACSM file from the book that you bought earlier. If it's not, buy preferred book and download ACSM file to your hard drive.

Note: ACSM file is not an eBook itself; it is a reference to an eBook. When you open ACSM file, actual eBook is downloaded from a remote source via Internet. ACSM files have an average size of 1-5 KB.


Step 1. Get started with Adobe Digital Editions

Follow these steps to get started with the Adobe Digital Editions:


Step 2. Obtaining Adobe ID and authorizing Adobe Digital Editions with an Adobe ID

The first time you open a protected book, ADE will ask you to authorize your computer. The best way to do this is to supply an Adobe ID, associating the book with your ID. If you later open the book on another computer, you can simply supply the same ID to open the book.

You can also authorize your computer manually. To do this click on the tab «Help» in the upper left corner of the application window, then on “Authorize Computer...” or you can just press Ctrl + Shift + U.

If you don’t have an Adobe ID, click the Create an Adobe ID link. After creating the ID on the Adobe website, you can close that browser window, return to ADE, and enter the newly created Adobe ID.

If an error occurs, try to erase all remnants of previous activations. To do that press Ctrl+Shift+D, then press "Erase Authorization".


Step 3. Using Adobe Digital Editions. Opening eBooks

Simply open the ACSM file or book file from Explorer or Finder or browser download window, and Adobe Digital Editions will launch. If ADE doesn’t launch automatically, start it manually, and then drag your book onto the application window. Download dialog will appear. The eBook will openautomatically. After the first opening of the eBook, you can find it in your Library in Adobe Digital Editions. To open Library click on an icon located in the upper left corner of ADE window:

All downloaded eBooks you can find in “My Documents\My Digital Editions” folder (Windows) or “Documents\Digital Editions” (Mac OS X).


Step 4. Transferring eBooks from or to a supported eReader. Authorizing of eReader

Connect the supported eReader device to your computer and launch Digital Editions. Digital Editions automatically detects the presence of your device. Both Digital Editions and the device must be authorized to be able to transfer protected content to and from the device. Unprotected content can be transferred to and from the device without authorizing either the device or Digital Editions, but we strongly advise authorizing the device. After connection, the device appears in the library section.

For authorization, do the following:

  • Select your device from bookshelves list:
  • Click the gear icon on the right and select “Authorize Device…”:
  • Select Adobe ID with which you want to associate the device and press “Authorize Device”.

To transfer the eBook to the device drag the eBook that you want to transfer to the picture of your device as demonstrated below:
