Then run the following command in the command prompt:

calibre-debug.exe C:\path\to\wherever\you\put\calibre-add-format-blank-txt.py

Here is the code.

def init_cache(library_path):
        from calibre.db.backend import DB
        from calibre.db.cache import Cache
        backend = DB(library_path)
        cache = Cache(backend)
        cache.init()
        return cache

import tempfile
temporary_txt_file = tempfile.NamedTemporaryFile(suffix='txt', delete=False)

cache = init_cache(library_path = 'C:\\Users\\<username>\\Calibre Library\\')


for id in cache.all_book_ids():
        cache.add_format(id, 'TXT', temporary_txt_file)

P.S. chaley, thanks for the similar python script you created in the templates, plugboards, custom columns thread a while back, you helped me figure out how to interface with calibre.
Does this look good?


I decided it wasn't worth trying to deal with json on other peoples' machines especially Windows, so it's all native calibre code.

Tested on a test library of mine, on a Win7 machine.

Thank you so much

I had a few problems getting the path right but eventually I got the message Welcome to the Interactive Calibre Shell. Does that mean its working?

I have nearly 6000 books so I don't know how long to leave it before I check in Calibre.
