[bugeyed]

I bought & dnloaded an ePub & when I actually chose to "save file" I noticed the file name was "URLLINK.ccsm". How does this work? At some point I opened it in Sony Reader Library& an ePub file appeared, but Calibre will not open it. It says that I must remove the DRM first. I think I have the tools to do that, but I would like to know how this process will work in the future. How can I tell if they are DRMd before I buy them? The site mentioned that I should use Adobe Digital Edition, but I am trying to make Calibre my one manager for my eBooks.

Thanks,
