I have an azw file that
Calibre with the plug-ins does is not, for some reason is not removing the DRM, although I do not always get an error message. My question is how can I tell if an AZW file has DRM or not?
I can't seem to find anything, either via a file viewer or in Calibre, that indicates this.
Can the presence of DRM be seen by something simple and easy to use?
Thanks.
