When you borrow a ebook from public Library, what you are really downloading is an .acsm file. There is a lot of confusion about this file type as the .acsm is not your actual eBook. It is just a link to your eBook that allows a program like Digital Editions to download the actual book, The idea that you could convert an .acsm file to a .pdf file is based on the assumption that the .acsm file contains all the text of a book, and that it’s just in the wrong format. That might be true if it was a .doc file, or any other text-based file. That is not what an .acsm file is.
There is no need for you to do any conversion. If you have Adobe Digital Editions installed, then all you have to do is open the .acsm file with that program. Then, the ebook download will continue. When the download is finished, you will have your PDF file.
When Digital Editions sees the .acsm file it will automatically download the PDF or ePUB file, which is the actual eBook, so you only remove drm from epub/pdf file, not from .acsm file, This is how to remove drm from epub/pdf file.

What is an .acsm file?
ACSM stands for Adobe Content Server Manager. That name gives a clue as to the purpose of these files — they are download manager files. They manage the download of your ebook.
The majority of the time, you don’t even see the .acsm file when you download an Adobe ebook. Usually the only time you see it is if you haven’t properly set up Adobe Digital Editions, or you don’t even have it installed. I can’t stress this enough: before you buy Adobe ebooks, whether PDF or EPUB, install the software you need! If you haven’t installed the correct software for any file type, your computer won’t know what to do with it.
