[Clark G. Flipper]

I had some funny effects that may be indirectly conncted to the DeDRM plugin, in a roundabout way. I am not concerned about the directory, but the filename itself. It happens reproducibly, thus:

Start with a DRM protected ebook, add it to calibre with installed DeDRM plugin. It gets decrypted.
Experiment 1) Copy the decrypted file to somewhere else and remove it from calibre. Forget about encryption, deactivate the DeDRM plugin. Now adapt the filename of the decryted ebook following your personal standars (e.g. remove spaces and special characters, abbridge, etc. pp.) Add this file to calibre again and watch what the GetFilename plugin derives as filename: the adapted one or the original one?
Experiment 2) Remove the ebook again, deactivate the GetFilename plugin, add the ebook again and watch what happens to the filename columns.

I would like to know if someone could reproduce the phenomena I experienced.
