We often download an .ACSM file after purchasing an eBook online, but it's not the eBook file. Here I will tell you how to convert ACSM to EPUB and PDF, then strip eBook DRM for reading on various devices.
How to Convert ACSM to EPUB books
Step 2 Register an Adobe Account, authorize your ADE Copy with your Adobe Account.
Step 3Open .ACSM with authorized Digital Editions to download eBooks.
Double click the .ACSM file, it will be opened with Adobe Digital Editions as default. And a window will be opened to show the downloading eBook (Network connection is needed).
If your .ACSM file is not opened by ADE as default, right click the file and select "Open with" -> "Adobe Digital Editions 2.0 ".
Output EPUB path of ADE is generally as follows.
For Windows: ...\My Documents (Documents)\My Digital Editions ...
For Mac: Users/Your computer name/Digital Editions ...
Or you can switch to "File" Menu -> "Item Info" -> "Location" to check the location of your downloaded EPUB book.
After downloading the eBook, you can delete the .ACSM or back it up for downloading the eBook again.
We can read the converted EPUB eBooks on Adobe supported devices like Sony eReader, Kobo reader, Android Devices (with reading apps like BlueFire installed) etc. Just copy the converted EPUB files to the specified eBook folder of your device with the USB cable connected to your computer. Make sure your eReader is authorized with the same Adobe account, otherwise you will be prohibited to open the EPUB books.
However, you can't directly read the books on Apple Devices (iPad, iPod, iPhone with iBooks) and Amazon Kindle titles. So we have to remove DRM from the eBooks, then transfer to anywhere as you like. Here is the best software for removing DRM from Adobe DRM protected ePUB.
How to remove DRM from ACSM (EPUB)
Step 1: Download Epubor EPUB DRM Removal.
Step 2: Run this program, if your EPUB files are converted from ACSM as the guide above, the program will find your EPUB files automatically. All you need to do is click the "Remove" DRM button.
More about ACSM file extension
The ACSM file type is primarily associated with 'Adobe Digital Editions' by Adobe. If your computer is asking you where to save the .ACSM file then your Adobe Digital Editions may not be installed correctly or not yet authorized. Often you can solve this issue by simply setting your computer to always use Adobe Digital Editions to open this type of file. (Right click an .ACSM file -> "Properties" -> "General" -> "Change" -> "Adobe Digital Editions 2.0" -> "OK")
