Converting ACSM files to ePub for the Sony eReader

December 29, 2011

I was fortunate to be gifted a Sony eReader (PRS-T01) for the holiday season and have so far spent much more time playing with the damn thing than I have reading books on it. I have been plugging away at the first Game of Thrones book as well but today I decided to buy another one for more casual reading. Unfortunately this book did not come as an ePub file or even a PDF, as I am used to, but rather a ACSM file. I did not realize this until after I had paid for it and downloaded it. Now the file did launch the Sony eReader software when double clicked but I don’t use that software, rather Calibre, and wanted to import it there. It would not recognize the file so I was forced to find a method to convert it.

After some research I was told to first install Adobe’s Digital Edition. This is not ideal as it involves yet another program, and a crappy flash one at that, but it was my only option. Once installed I was able to open the ACSM file which then downloaded the book. It turns out that this file is not really the eBook itself, but rather a voucher for the actual book which you can only redeem using Adobe’s software. After it has been downloaded I suggest you close the program and never revisit it unless to fetch another ACSM as it is terrible. It will reveal to you no method to access the ePub file it just downloaded, but alas it has done just that. You will now find an ePub file in your My Documents folder under My Digital Editions. Take that file and import it to Calibre, and go ahead and delete Adobe Digital Editions after that.

  1. Thank you soooo much! Had to use a virtual machine with windows (in my opensuse) just to run adobe. Was able to read it (also on my kobo device by the way, which is great). But I wanted the epub for backup purposes. I didn’t know it was just in the my documents folder. Awesome!

  2. Ok, spoke a little bit too soon. I have the epub file, but cannot open it with calibre, because it is drm protected… well, I will figure it out later 🙂

  3. Thank you! Thank you! Thank you!!!!!!
    I was going insane trying to figure out a way to read my school book!!! I thought it was because I have a Mac. But I found the PDF and transferred it to my reader and now I’m good to go!! 🙂

    Thank you, thank you again!!!

  4. i also have problems, but from an other kind. i first had bought the book (in acsm format) and than installed adobe digital editions. i even cannot import the file into adobe..library. does anyone knows how to solve this? i also cannot import it into the sony ereader software on my computer.
