I have some csv files that are larger than github\'s file size limit of 100.00 MB. I have been trying to use the Git Large File Storage extension.
https://git-lfs.gi
If you know which commit introduced the large commit, you could also try squashing that commit with the subsequent commits that introduced Git LFS.
For example, if the large commit was three commits ago (as revealed by git status), you could do the following:
git rebase -i HEAD~3
Then, replace all "pick" usages after the first one with "squash" in the interactive dialog.
Then,
git push origin --force
