Although I agree that the file structure under Calibre does not need to be user addressible, the "Send to Disk" and "Send to Device" filename filters really need work. Since filenames are just another attribute of the document records in the internal db, why not have it dynamically renamed according to a user modifiable pattern.

So, if I fix my metadata, adding correct authors, series, book numbers and titles, shouldn't I be able to pick an export filename pattern like:

Author - Series - Number - Title

This way I can share books with people who don't use Calibre.

Even internally, I know I shouldn't be looking at the folder structure that Calibre uses, but when I do peak under the hood, I see alternative languages, naming patterns, grouping, etc. It's a mess. If the ID in the parens is all that really matters, why isn't renaming the file and folder according to the metadata possible?

We did an account management project at work that used a similar idea, except we used a double underscore, followed by a 5 digit hex code to be the ID, and this was used to link a record entry, a file system folder, and an email repository folder in Exchange. We could freely rename all of them as long as we kept the ID section intact. We later wrote a function to do so for us based on criteria in the record.
