What is an ACSM File
First of all, you need to know what an acsm file is before downloading Google Play Book to your computer. Because the majority of the books you download from Google Play website are acsm files instead of PDFs or ePub books. So it's very necessary to explain what is an acsm file.

Weird question:
How does ADE "know" which Google account to authorize the ebooks to?
I logged in with an Adobe ID that has no connection to my Google account.
Download the ACSM and it open just fine in ADE
Then I can transfer it to calibre without stripping the DRM! I can even convert to TXT and other formats.
Furthermore, I logged out of ADE and it won't open the ebooks, but if I go to explorer I can open the epub in Calibre and convert it and read it etc.
What's going on here? This is driving me mad!
1. The .acsm file is the link to download the google play books. So if you authorize the adobe digital editions with your adobe id, it will help you download the acsm file to epub/pdf.
2. Some downloaded epub are encrypted pdf/epub are encrypted with drm and some are not.
3. If you've already install the calibre drm removal plugin, when you add the google books to calibre, the drm will be removed automatically. That's why you can convert them to other format.
Bait and switch. To get it to download a full pdf you will be instructed to pay for a full license of the software -- it is misleading that the article claims you can do this with a free edition of the software.
"Your ebook has decrypted. The file just save 20% of ebook content. Please register the software, then get full content and the valid ebook format."
