#96 Update e-book path

[Anonymous]

I usually enter information about books placed in a temporal directory, but later I reorganize the location of books in different directories. It would be nice to automatically update the path of the book. Something like "Search the missing link to the ebook in the following directory". I think that It would be also useful in a lot of other circumstances.

Thank you very much

I intend to support such a feature, by adding a hash of the file, and searching the db if the file already exists.
