Hello,
The BFO file is very large (80mb) & has a lot of garbage. While downloading, your server breaks the stream many times & we are unable to download it.
I was able to download it on my google cloud server which has the fastest speeds.

But it contains all those contracts which are not traded at all. Please only provide SENSEX, SENSEX50 & BANKEX contracts in this file as BSE Stock Derivatives has very less volume.
Also 80mb enormous size for the file, please check what is the reason.
Mostly, the combined size of ALL exchanges’ symbols is around 10-15 mb, whereas this data is only for BFO.
