Adobe Digital Editions ("ADE") is used by CloudPublish to make downloads available with "hard DRM" applied (see CloudPublish DRM options). When you trigger an ADE download, the user will be offered a file that must be opened with Adobe Digital Editions (and cannot be opened with a normal PDF reader). When opened, this will in turn cause the encrypted eBook to be downloaded.
The following instructions describe the process from a user's perspective:
- You will require a copy of Adobe Digital Editions to be installed on your PC/Mac; this can be downloaded from Adobe.
- You will also require an Adobe ID. This links your copy of Digital Editions to you personally.
- Download the eBook (i.e. from your CloudPublish-enabled website).
- This will cause a file named “URL.ascm" to be downloaded. You should simply open this file using Adobe Digital Editions.
- Adobe Digital Editions will then download the eBook itself (some eBook files are large and this step may take some time), and it will be available in your Adobe Digital Editions bookshelf, from where you can read the book offline on your own computer.
Once you have the eBook in Adobe Digital Editions, you can copy it to a handheld device so that you can read it while you are on the move. There are lots of compatible apps / devices listed here.
- You will require an Android or iOS device, or another device that is compatible with Adobe Digital Editions (e.g. Kobo)
- On Android or iOS, you will also require an eReader app. We have tested and recommend the Bluefire Reader app which is available free of charge on Google Play or Apple iTunes.
- You will need to authorise your eReader (or eReader app on Android / iOS) with your Adobe ID (see above - this must be the same Adobe ID that you use with Digital Editions) The procedure varies according to the eReader software, so please check your eReader's instructions.
- All you need to do now is plug your eReader device into your Mac/PC, and it will show up as a device in Adobe Digital Editions. You can then drag the eBook from your bookshelf onto the device, and then read it from your device, assuming that you have linked with your Adobe ID correctly.
Note that Kindle devices cannot normally be used in this way. You may however be able to install an eReader such as Bluefire on an Android-based Kindle Fire, but this is technically advanced (requiring the installation of a package explorer and then the app's package, not via the app store), and probably not recommended for the average user.
It is sometimes also possible to directly open the URL.acsm file from the eReader app, rather than going via Adobe Digital Editions (this varies depending on the app).
