How to change the default "weight" for the transferred ftplib file?

Question

Python

There is such a code, but by default the "weight" of the transferred file is only 8192 bytes, how can I change the default setting to be able to transfer larger files?

The code

import ftplib

filename= "*****.xlsx"

ftp= ftplib.FTP('*********')

ftp.login('*******', '********')

ftp.cwd('*******')

uploadfile= open('(**/***************/*******', 'rb')

ftp.storlines('STOR ' + filename, uploadfile)

Answer 1

And if you first request the file size from the ftp server
ftp.size('ftp_dir/filename.zip')
