Fixing the “GH001: Large files detected. You may want to try Git Large File Storage.”

I just migrated my repositories from BitBucket to GitHub but, suddenly, I received an interesting error when I tried to push a repo with some large files inside.

remote: error: GH001: Large files detected. You may want to try Git Large File Storage — https://git-lfs.github.com.
remote: error: Trace: b5116d865251981c96d4b32cdf7ef464
remote: error: See http://git.io/iEPt8g for more information.
remote: error: File fixtures/11_user_answer.json is 131.37 MB; this exceeds GitHub’s file size limit of 100.00 MB

It turned out that GitHub only allows for 100 MB file. The problem is that I can’t simply remove the file because it is tracked inside the previous commits so I have to remove this file completely from my repo. The command that allow you to do it is:

git filter-branch -f --index-filter 'git rm --cached --ignore-unmatch fixtures/11_user_answer.json'

At which point you can push the file to GitHub.
