Hi!

I am new to Calibre and I loved the program. A friend recommended it and it is really good. Congratulations on everybody that helped the project!

I am writing because I have a lot of e-books and some of them are duplicated in different formats. I saw Calibre can edit EPUB and AZW3. I did some test and edited a copy of my library and it modified the original file. I saw some options talking about ORIGINAL_EPUB but it didn't make a copy, it changed the "master" file. Maybe only converting makes this copy?

Can I protect the files from being modified like iPhoto, Picasa or Lightroom (if someone uses them)? For example, when I change the metadata it doesn't modify the EPUB or AZW3 file, but an external file. If someone accidentally edit the EPUB I hope it changes a copy or don't change anything.

Is possible? I can modify the file to be read only but I don't want to do that every time I import a file.

Thanks!
