I uploaded two files (220MB + 830MB, 1.05GB in total) in one of my github repositories.

I wanted to reduce the size of the big file (830MB).
So, what I did was I erased the file and replaced with another file(170MB).

I expected my github to be around 400MB, however it becamse 1.21GB.

I did some search and found that the file could be still remaining in the repository history. So I tried to use the bfg repo, but that didn’t seem to still work.

Is there any way to fix this?
