How to Open ACSM File

Posted by on .

open acsm file

After downloading an ebook online, you will probably get a acsm file. At this time, I believe that most of us will double click it and soon find out that we failed to open the file. Now you may be wondering how to open acsm file. Don't worry, you will find the answer in this post which collects comprehend information regarding ACSM file, and provides you with a step-by-step guide on how to open acsm files on Windows, Mac, iPad, iPhone, Android and even on Kindle.

Part 1. Open ACSM File on Windows/Mac

Step 1 Download and run Adobe Digital Editions to your PC/Mac.

Adobe Digital Editions for Windows download: ADE for Win (8.13MB)

Adobe Digital Editions for Mac download: ADE for Mac (23.2MB)

Step 2 Authorize Your Computer with Adobe ID.

The first time you run Adobe Digital Editions, a window will pop up asking you to authorize your computer with your Adobe ID. If you do not have an Adobe account yet, you can create a new one. Then you need to input your Adobe ID and password to authorize your computer with ADE.

Step 3 Open ACSM with Authorized ADE.

In this step you should first download the ACSM files to your computer. When you get the ACSM file, double click it or just drag and drop it to the main interface of Adobe Digital Editions, and it will be opened with ADE automatically. If not, right-click the file and select "Open with" -> "Adobe Digital Editions 4.5 ". Then a window will open showing the downloading process (Network connection is needed).

After the downloading process is completed, your ACSM files will be opened. Now you can review them in the library. And here I want to stress that the ADE will convert your ACSM files to real ebook file epub or pdf automatically. You can find the downloaded epub or pdf books here. You can also switch to "File" Menu -> "Item Info" -> "Location" to check the location of your downloaded epub/pdf books.

For Windows: ...\ My Documents (Documents)\ My Digital Editions ...
For Mac: Users\ Your computer name\ Digital Editions\ ...

Now your acsm files are downloaded to Adobe Digital Editions with .epub or .pdf. These two formats are real ebooks. Make sure your eReader is authorized with the same Adobe account, otherwise you will be prohibited to open the EPUB books.

Note:

You can only read the ACSM on Adobe Digital Editions. It means you cannot open the books with any other EPUB Reader or PDF Reader on Windows or Mac. The reason is that the ACSM files are protected with Adobe DRM, which made a limitation on the ACSM to be only compatible with ADE. Here comes the best solution--remove Adobe DRM and convert ACSM to PDF/EPUB/Mobi to read on any device you want.

Don't worry. It will be much simple to do that. Just be equipped with the most powerful tool Epubor Ultimate to help you.

Above is the easiest way to open acsm files on Windows/Mac. I believe it is enough for most of you to open your acsm files. But next I will also add more information about this topic which you may concern very much.

Part 2. Open ACSM File on iPad/iPhone

How do I read an ACSM file on my iPad/iPhone? If you have this question, there are two methods available for you.

Method 1. Remove DRM from ACSM and Open with iBooks

When asked about how to open ACSM file on iPad/iPhone, the most recommended method is to transfer ACSM from ADE to the device. But as I have mentioned above that Apple devices are not included in the Adobe supported devices. Therefore, we must convert ACSM to EPUB and remove DRM before transferring to iPad/iPhone. Then we can open these converted files with iBooks.

Method 2. Open ACSM with ADE Alternative on iPad/iPhone

In fact there is another method. We can install a third-party ebook reader app which supportes ACSM files on our Apple device. I like to call it "Adobe Digital Editions alternative for iPad/iPhone ".

Here I suggest you try Bluefire Reader. Install the latest version on iPad/iPhone at first. Then download the ACSM files to your computer, send them to your email box so that you can get them to your iPad/iPhone. What you need to do next is to select the ACSM, choose "Open in 'Bluefire Reader''' and "Read Now".

Part 3. Open ACSM File on Android

Here are 3 methods for you to Open ACSM file on Android.

Method 1. Transfer ACSM from ADE to Android

It is easy to open ACSM files on Android, since most Android phones and tablets are Adobe supported devices. After you download an ebook with ACSM extension, please open them with ADE on your computer first. Then you need to transfer them to your Android device with USB cable. You can open them directly with the same Adobe ID registered.

Method 2. Remove DRM from ACSM and Open with Google Play Books App

If you don't want to be linked to Adobe ID all the way, you can remove the Adobe DRM from ACSM files, and open them with Google Play Books App. The tool you need here is also Epubor Ultimate.

Method 3. Open ACSM with ADE Alternative for Android

The same as iPad, we can also install ADE alternative app on Android to help us open ACSM file instead of ADE. Download and intall Aldiko from Google Play App Store. You need to input your Adobe ID informations. Then just drag the ACSM file to the app and open it to read.

Part 4. Open ACSM File on Kindle

If you want to open ACSM files on your Kindle device, the steps will be a little different. The reasons are as follows:

--There are no ADE alternatives app for us to install on Kindle.

--Though we can remove DRM from ACSM and convert them to epub or pdf with ADE, Kindle doesn't support these two formats at all.

So the perfect solution is to convert ACSM to kindle format. To open ACSM on Android, iPad, iPhone, Kobo or Sony eReader, we just need to remove the Adobe DRM without need to convert formats. But for Kindle, we must remove DRM and also convert the format to Kindle format. Don't worry! Epubor Ultimate, the tool I mentioned above can still do the job!

Step 1 Download and run Epubor Ultimate.

Step 2 Open ACSM with Adobe Digital Editions and get the converted EPUB/PDF files.

Make sure you can open ACSM files with ADE on your computer. Then run Epubor Ultimate. At the left column, you can find your your ACSM books under the "Adobe" tab.

Step 3 Convert ACSM to Kindle format.

Just drag the books from the left column to the right blank, choose Kindle mobi/azw3 as the output format and start converting.

Step 4 Transfer converted ACSM files to Kindle with USB.

All you have to do now is to connect your Kindle devices to the computer with USB and transfer the converted ACSM files in Kindle format to the Kindle folder. Now everything is done. Just open it on your Kindle to enjoy your reading.

Thanks for using our software!
Yes, Epubor can't convert .acsm file to Kindle books directly.

ACSM file is the key to download Adept ePUB/PDF books, so you need open acsm file with Adobe Digital Editions to download Adept ePUB/PDF book files at first, then use Epubor software.

After you download ePUB/PDF files, then drag to Epubor software, and choose output as Kindle, then click "Convert".

All done.

Hello,

I have been having an issue since few days and Kobo support can't help.

I bought a book on their online service, and tried to open it with ADE but get following error :

Error getting License. License Server Communication Problem:
E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER

This is the second book I buy with them, I did not have issue to open the first .ACSM file and to transfer it to kindle. The Adobe ID I use has the same email address on the kobo service, I tried to reauthorise ADE various times but it did not help. Also to download new copies of the -ACSM file after installing ADE.

Can you please assist?

Thank you,

Ale

Hi,

If the ADE told you "Error: E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER", that indicates the authorized account is not compatible with the book. If you are sure the Adobe account has no problem, please contact the eBook retailer support to bind the book to your Adobe account.

You haven't said how one can open an acsm file with an Android 5.1 device. I have installed the ADE android app, but can't find out how to link it to acsm files so that it will open them. The Default App Manager doesn't help. Can you help?
