Calibre 5.2.0 how to Modify or compile python-lib.bypy.frozen.
this can modify the pylib.zip file before.
I want to modify in filenames.py:
def delete_originals(self):
import win32file
for path in self.handle_map:
#win32file.DeleteFileW(path)
os.remove(path)
self.close_handles()

You cant modify it. If you want to run calibre from source, follow the instructions here: https://manual.calibre-ebook.com/develop.html

And might I ask why you want to make that change?

When adding a book to the Calibre library, the book name will be converted to English characters.
It is very inconvenient to search by book name in the future.
So, need to modify backend.py and filenames.py.
When there are non-English directories or files in the Calibre library, using win32file.DeleteFileW(path) to delete the file will cause the program to crash, and need to use it instead os.remove(path).
