I download epub and pdf format books from the public library and a private bookseller.  The download comes with a .acsm suffix instead of epub or pdf. When I try to transfer these to my Nook Color use ADE they are not accepted by ADE and do not show in the library window.

How can this problem be solved?

A. 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, When Digital Editions sees the .acsm file it will automatically download the PDF or ePUB file, which is the actual eBook,
If you do have Adobe Digital Editions installed and authorized correctly, then you won’t even see the .acsm file at all. It will do its job in the background of your ebook download. The purpose of this file is to communicate with Adobe’s content server and register the ebook to the Adobe ID that you have used to authorize ADE. If you don’t know how to do the authorization process, 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.

EPUB, MOBI, AZW and PDF eBook DRM Difference

You should know the difference between EPUB, MOBI, AZW and PDF eBook Formats.

EPUB

The EPUB format is an open standard. That means it is free and publicly available though there are specific rules for its usage. The EPUB standard is maintained by the International Digital Publishing Forum (IDPF), a global trade and standards organization.

MOBI

The Mobipocket ebook format is another open standard for eBook publishing. It was bought by Amazon. It is also cross-platform. eBooks in this format can have the .prc or .mobi extension.

MOBI formats can take complex content, include advanced navigation controls, supports indexing and a high degree of compression. For instance, readers can add their own pages, freehand drawings, annotations, highlights, bookmarks, corrections, and notes if devices support it. It can also include a dictionary. MOBI formats are suited for smaller screens because the image size limitation of 64K. The image size and image format (GIF) puts the format at odds with larger display devices like tablets.

MOBI can also display reflowable content and fixed width layout.

AZW

AZW is a proprietary format developed by Amazon specifically for the Kindle eBook reader. It has its roots in the MOBI format but has better compression and encryption apart from a few more changes. The AZW format has found its place in many platforms with Kindle reading apps apart from Kindle. But AZW files can only be obtained from the Amazon online bookstore.

AZW format is DRM (Digital Rights Management) restricted and is locked to the device id which is registered automatically with the user account of the Kindle purchaser. But DRM free books also carry the AZW extension but they are really no different from MOBI files.

The PDF format supports fixed width layout and reflowable content. Because of their commonness, many tools exist to create, edit, and secure PDF documents.
