I'm still struggling a bit to figure out the best way to manage my reader. Originally, last year, I installed Sony Reader Library. Shortly after I jumped into Calibre. Calibre was very nice, although I still work to make everything more efficient. Yesterday, having some holiday time, I checked my firmware for any updates and ended up downloading "Reader for PC" from Sony. Can anyone honestly say what that piece of work was really supposed to do? It messed me up. Here's what happened to me:

I needed to delete a book. I could not delete the file from the device using Calibre. Reader Library would not let me delete from the device because the file was synced. Since I had never had this issue before I suspected that Reader for PC was at issue. However, when trying to delete using that software, I found no way delete a file.

Finally, I deleted "Reader for PC" from my system. I kept Sony Reader Library because I need it for Library borrowing. Apparently, Calibre has no way to link to Adobe Digital applications to get a borrowed DRM file. I guess you also need Sony Reader Library in order to buy from the Sony store.

Now Calibre let me delete the book from my device.
