The release notes (in a comment at Alf's Blog) say that there was also a change in the script that fixes up zip files, [EDIT] but the plugins that include the zipfix.py script weren't updated.

If you don't use calibre and the plugins, it seems there's now a Drag&Drop tool for windows that has similar functionality to the Mac OS X DeDRM AppleScript that Alf wrote.

I use calibre and the plug-ins. Some of that stuff only applies to a Mac. I'm not sure which is which. All I've ever done (or known to do) is upgrade the plug-ins. I'm in a PC environment with multiple flavors of Windows from XP/home to 7/64.

If you use calibre, the plugins are certainly the best way to go, IMO.

This is just silly. What a strange world we live in.
The ability to change an ebook from one form or another is no different than
buying a CD, and then recording it to cassette tape so you can play what you have spent money on in a different format. Are they going to make that illegal too?
I know they talk about it, but as long as you are not distributing it to others, I don't think anyone has ever gotten in trouble for that.

Do they do it to FORCE you to pick their reader over another? That's senseless as well.
Don't these companies realize that you will likely spend more money on ebooks over time than you will on the reader itself...I would think that B & N would would specifically NOT use DRM, and encourage Kindle readers to spend money on their books and convert them just so they COULD read them on a Kindle...this is money they are losing, no?

This it like them saying: "No, I will NOT sell you 500 bucks worth of ebooks because you won't spend 250 on my reader!"

It's not funny. Nobody here is going to help you steal books. We don't do that here.

It seems that although Apprentice Alf's retired, some of his friends are continuing to support the dedrm tools.

There's now a 3.3 archive containing a few bug fixes for the tools, including changing the plug-ins for ePubs to use the zipfix script first.

I can't give a link to the tools, of course, but it can be found in the usual blogs.

There are advantages to an open and a closed format.

this might be a bit OT but it is still about technology.

Back in 1983 there was a video game crash. Countless companies got into video games and made utter crap. The consumer was confused and the platform makers did not have any form of encryption to really prevent this.

A few years later Nintendo came out and they had a very strict policy that pretty much would prevent other companies from licensing. Some attempted but lawsuits tried to block them (google Tengen tetris..it was interesting)

It should be noted that in this industry the systems are sold at or below cost to be made up in the cost of games. 3rd party game companies pay a fee for each one sold. So eventually there is a ratio to profitibility

Fast forward a bit to say today. apples ipad, iphone/ipod touch do well but the apps store isn't open... this is also why Android I feel will eventually overtake apple (that and the fact that the hardware sells clones)

Since hardware prices keep going down it only makes sense that the makers of these e readers seem at least a tad protective of encryption and how things work. If Amazon didn't want it to be a open system they shouldn't have made it with linux..heck nook has android on it which again is a open system.

If file conversion wasn't allowed (legally here..I have some word docs that were put to azw for a class) then the devices wouldn't sell.it is impossible to day to have a totally closed system and expect it to last forever like that.

Tools is now up to 3.6 - I gather changes in regular and topaz kindle books drove the fixes.

[QUOTE=curstpriest;1245528]II mean honestly, I can't think of a single person I know or have ever met who has never made use of illegally downloaded music (knowingly, or unknowingly, as a gift or whatever)/QUOTE]

I think it depends on age. I didn't get an ipod until after the crash of Napster, so the issue of illegally downloading music never occured to me.

I never smoked weed, either, and I can't blame age. I guess I was just a nerd, and it seems too late now. I guess I will wait until I need it for medical reasons. . .

I don't use the Calibre's k4mobidedrm plugin. It renames the file extension from .azw to .mobi. I want .azw files in Calibre, to keep as source files to convert my books from.

So, I use the KindleBooks tool. Has that been updated?

[EDIT] "Last modified [Jan 28, 2011]" ...it would appear so.

Can't you set calibre to convert to .azw?

I thought Calibre did not alter the original file in any way. I thought it reads the original and then processes that information and creates a new file in whatever format you have selected. I would imagine you could change the file's extension (maybe outside of the calibre process/library)

chyron8472 · 02-19-2011, 01:27 AM

ooh... this new DeDRM_WinApp is handy. I don't need to copy/paste my pid/serial anymore as it saves my preferences, and it handles more ebook drm than just Amazon's.

It does, however, rename the file to .mobi

but I can rename that easily.

I don't like it when Calibre does it because I have to remove/add the ebook in Calibre after I change the file extension anyway and it bothers me to have to add it twice.

[edit] I do wish that there was a standalone version of this, so that I could use it in the case that I was on the go and away from a machine with python on it. [/edit]

Nope. You can convert from .azw but not to it in Calibre. Technically, .azw and .mobi are the same thing anyway, so Calibre doesn't bother to include both file extensions as an output option, only .mobi. In a way, this is a bonus for me as having .azw files in Calibre ensures that I have a source copy of my Amazon-bought ebooks which will never be overwritten by Calibre.

My experience has been that if an .azw has drm on it, Calibre's k4mobidedrm plugin breaks the file and has Calibre add it to the library as .mobi. It's not altering the file in changing the extentsion because .azw and .mobi are basically the same thing. However, I want azw files in Calibre to use as my primary input files.

Yes, I can open the liberated file's location, change the extension, delete the original entry in Calibre and re-add the ebook to Calibre again, but it means fewer steps if I just use drm removal tools outside of Calibre instead.

This would be fairly easy to achieve by editing a single line of code in the plugin. But I can't for the life of me see any measurable advantage to it, since azw = mobi. Must be an OCD thing.
