ACSM files (files that end with .acsm) often cause confusion for those who are unfamiliar with them. This post will tell you what you need to do to open them.
- ASCM files are part of Adobe’s eBook DRM.
- ACSM files are not supposed to be the full eBook. They are small files that manage the download of the eBook.
- ACSM files are made to be opened with Adobe Digital Editions. This is a free program from Adobe that was created for their eBook DRM. Get it here.
- To open an ACSM file, simply double-click it, and it should open in Adobe Digital Editions if you have that program installed.
- Opening the ACSM file in Adobe Digital Editions will allow it to continue your eBook download. When it’s finished you’ll have a PDF or ePub file.
If you’re downloading an .acsm file, it’s probably an eBook with DRM, so you should also make sure that Adobe Digital Editions is properly authorized. I have a post that explains this process for you. Authorizing your copy of Adobe Digital Editions with an Adobe ID will allow you to use your eBook on more than one computer as well as your mobile devices that support Adobe’s DRM.
ACSM files on iOS, Android, or eReaders
Sometimes people will try to download a DRM-protected PDF or ePub directly to their iPhone/iPad/eReader/Android device. That won’t work because the .acsm file can’t be opened in any apps on those devices. The eBook must be downloaded to your computer first, through Adobe Digital Editions. There is no version of Adobe Digital Editions for iOS, Android, or eReaders. After you’ve downloaded the ebook to your computer, you can then transfer it to your device.
Convert .acsm to PDF?
Often when people are unfamiliar with .acsm files they think they should convert the file to a PDF. This is not possible, and it arises from the mistaken assumption that the .acsm file is the eBook and they’ve somehow downloaded a weird file type. If you have an .acsm file, the only thing you can do is open it with Adobe Digital Editions. That will continue the eBook download process, and once that’s finished, you’ll have your PDF/ePub file.
It’s easy for your computer’s file associations to get messed up when you try to open a file in the wrong program. If you’ve downloaded an .acsm file and you tried to open it in, for example, Adobe Reader or Adobe Acrobat, you might have checked the little box that says “Always open files of this type in this program”. If you did that, you’ve screwed up your file associations and .acsm files will always try to open themselves in the wrong program.
To fix this, you’ll need to edit your file associations. Instructions on now to change file associations on a Mac | Instructions on now to change file associations on Windows Vista & 7
How To Open ACSM Files
There are always three ways to open a file on your computer:
1. Double-click it. It will open in the program that your computer has associated with that file type. See above if you’ve associated .acsm files with the wrong program.
2. Right-click it. Right-click the file, go to “Open With”, and choose Adobe Digital Editions.
3. Open manually from inside the program. Open Adobe Digital Editions. In the upper left area, find LIBRARY. Click the downward arrow next to Library, and click on “Open”. Find the file on your computer. It should be in a folder called My Digital Editions, which is in the main Documents folder.
Get some free ebooks!
The big ebook news this week is that official Harry Potter ebooks are now available on the Pottermore website.
When I read about this, the first thing I wondered about was what format the ebooks were being made available in, and what kind of DRM they were using. From looking at their supported devices FAQ page, at first it appeared that they were using typical Adobe DRM, since they mention the use of Adobe Digital Editions. However, it seems to be more complicated than that. In order to get ebooks onto a Kindle, for example, they’ve somehow set it up so that you link your account so that the ebook can be delivered to your Kindle. The same goes for your Sony Reader, Nook, or Google Play accounts. Additionally you can download an ePub to your computer. It also appears that you can transfer the ePub to other eReaders with ADE in the same way I’ve outlined on this blog before.
There seems to be more to it, though. Apparently when these ebooks were first announced, the people behind Pottermore claimed that the ePubs would be without DRM. Now it’s become clear that there is some kind of DRM on them, which people are calling “watermarking”. I’ve never even heard of that term being applied to DRM. The Digital Reader has a post about this DRM method and how it was already hacked.
This article on The Guardian is quite interesting. It talks about how Pottermore has managed to force Amazon to bend to its will.
“Instead of buying the ebooks through the Amazon e-commerce system, the buy link takes the customer off to Pottermore to complete the purchase, with the content seamlessly delivered to their Kindle device. It is the first time I’ve known Amazon to allow a third party to “own” that customer relationship, while also allowing that content to be delivered to its device. Amazon gets something like an affiliates’ fee from this transaction, much less than it would expect to receive selling an ebook through normal conditions.”
This is very unlike usual Amazonian practices. I assume it’s because Pottermore wouldn’t allow them to sell the ebooks in any other way, and it shows how much power the Harry Potter brand has. There is another article at FUTUReBOOK by the same author that delves more into this Amazon situation and how DRM is applied across different platforms. The whole system must have been a pretty big undertaking for all companies involved.
All in all, it’s cool to see that there are now official Harry Potter ebooks because that only enforces the idea that ebooks are here to stay, in one form or another. I probably won’t buy them myself since I already own the whole series in old-fashioned paper. Will you?
eBooks have grown in popularity over the past couple years, largely due to new ebook readers that have become available and more affordable. Many people are giving ebooks a try now that they have become more of a mainstream product. eBooks are excellent for a variety of reasons, but there are some situations in which purchasing an ebook is not the best choice. The following situations are those that I have identified as the five most common.
When You’re Not Comfortable With Technology
In order to successfully use an ebook, you must be able to install software, download a file, and open the file in the correct program on your computer. If you want to read the ebook on a mobile phone or e-reader device, then you need to know how to transfer files between your computer and that device. You might also need to install a program or app on your mobile device. If you’re not already comfortable with these processes, ebooks might be difficult for you to use.
When You Need a Printed Book
Many ebooks, if not most ebooks, are not printable. Even ebooks in PDF format are often not printable. This is because book publishers are concerned about copyright protection. They disable the printing function so that people can’t make illegal copies of the book. Other ebook formats, such as Mobipocket or Microsoft Reader, don’t have a printing function at all. In general, ebooks are meant to be read on your computer, e-reader, or other mobile device.
Besides the question of whether or not the ebook will be printable, printer paper and ink is not free, so you’d end up paying for the ebook and then paying more to print it yourself. If you need a printed book for any reason you should buy the paperback or hardback version of the book.
When You Want To Give The Book as a Gift
eBooks are often not able to be given as a gift for the same reason that they aren’t printable. Book publishers are very concerned about software piracy, so most ebooks are sold with DRM (digital rights management), which ties the ebook to a specific user account. If you email an ebook to someone else, or give it to them on a disk or flash drive, the ebook won’t open once it’s on their computer because their software is not registered to your user account. If you would like to give an ebook as a gift, look for a gift certificate option instead of buying the ebook yourself.
When You Don’t Know What You Need
Before you buy an ebook, it’s best to do a little bit of research to find out what type of ebook you need. eBooks come in different formats, and not all work on every operating system or mobile device. If you don’t already know, find out which operating system your computer or device uses. From there, you can research ebook formats and determine which format will work on your operating system. Next, you should install any software that’s required for that type of ebook. Once you’ve taken those preliminary steps, you’ll be ready to find ebooks that you want to read.
When You Want The Text Read Out Loud
“Text-to-speech” is sometimes a feature that people look for when buying ebooks. Unfortunately, it is often disabled in the ebook (again, because of DRM), and sometimes it’s just not available at all. Even when it is available, it’s just not very good. Sometimes people even buy ebooks with the intent of putting them onto their iPod to listen to. That is not what ebooks were designed for, and it doesn’t work at all because ebooks don’t contain an audio track. When you want an audio recording of a book, the best option is to buy the audiobook instead of the ebook.
The situations I’ve explained above are not only common situations in which you should not use ebooks; they are also some of the most frequent reasons why people get frustrated with ebooks. When someone buys an ebook with the hope that it will do something that ebooks aren’t capable of, they quickly become disappointed.
eBooks aren’t meant to replace paper books, and you don’t have to use them. It’s best to think of ebooks as just one book format that is available. You wouldn’t buy an audiobook when you wanted a paper book, and likewise, there is no need to buy an ebook if it’s not really the best choice for you. Use ebooks when you want a book in digital format to read on your computer, e-reader, tablet, or mobile phone.
If you want to read ebooks that are protected by Adobe DRM on your iOS device (that includes iPad, iPhone, and iPod Touch) the app I recommend is Bluefire Reader.
Most of the ebooks being sold by mainstream publishers that are in PDF or ePub format are protected by DRM. Book publishers, just like music publishers, are concerned about software piracy, so they require ebook stores to use Adobe’s DRM on the ebook downloads. Programs like Adobe Reader and other standard programs or apps that read PDF files aren’t set up to deal with that DRM, so you need an app that can handle it.
Here is what you will need to do:
1. Follow my previous instructions for how to set up Adobe Digital Editions correctly. You’ll need to install it and then “authorize” with your Adobe ID.
2. Get the Bluefire Reader app for your iOS device. Download it from iTunes and install it on the device.
3. The first time you open Bluefire Reader, you’ll be asked if you want to authorize it with your Adobe ID. You should go ahead and do it. Just follow the instructions given.
Make sure to use the same ID that you used when you authorized Adobe Digital Editions on your computer. That is how Adobe will allow you to use your ebooks on both your computer and the iOS device.
4. If you haven’t already, get an ebook that you want to read.
5. Transferring Files
Note: This will only work with iOS 4 or later. If you have an iPad you should already have that, but if you have an older iPhone or iPod, update the OS so that you can transfer files from your computer to the device.
a) Connect your device to your computer.
b) Open iTunes and click on your device. It should look something like this:
Obviously if you have an iPad it will say “iPad” or whatever you named your iPad, etc.
c) On the top-center area of the screen, click Apps. In iTunes on my computer, it looks like this:
d) Scroll down to the “File Sharing” section, which should be at the bottom of the screen. Select the Bluefire Reader app from the list, and click “Add”. On my computer it looks like this:
e) Now you can find the ebook that you want to transfer. If you bought a DRM-protected Adobe PDF or ePub file, it should be in a folder called “My Digital Editions”. Any non-DRM ebooks will be wherever you put them on your computer.
It might sync to your device automatically or you might have to perform a sync on your own. After that you should be able to open Bluefire Reader on your device and see the ebook.
I recommend that you find ePub files rather than PDF whenever possible. It seems that most e-readers and ebook apps display them a lot better because ePub files are reflowable, which means that the text of the book can rearrange itself to accommodate your screen size much easier than in PDF files.
