Tell your collaborators to rebase, not merge, any branches they created off of your old (tainted) repository history. One merge commit could reintroduce some or all of the tainted history that you just went to the trouble of purging.

After some time has passed and you're confident that git filter-branch had no unintended side effects, you can force all objects in your local repository to be dereferenced and garbage collected with the following commands (using Git 1.8.5 or newer):

git for-each-ref --format='delete %(refname)' refs/original | git update-ref --stdin
git reflog expire --expire=now --all
git gc --prune=now

Counting objects: 2437, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (1378/1378), done.
Writing objects: 100% (2437/2437), done.
Total 2437 (delta 1461), reused 1802 (delta 1048)
Note that you can also achieve this by pushing your filtered history to a new or empty repository and then making a fresh clone from GitHub.

TO FIND BIG FILES ON THE REPOSITORY.
Some scripts I use:

ListBigFilesOnTheGitHistory.txt

git-fatfiles:

git rev-list --all --objects | \
    sed -n $(git rev-list --objects --all | \
    cut -f1 -d' ' | \
    git cat-file --batch-check | \
    grep blob | \
    sort -n -k 3 | \
    tail -n40 | \
    while read hash type size; do
         size_in_kibibytes=$(echo $size | awk '{ foo = $1 / 1024 ; print foo "KiB" }')
         echo -n "-e s/$hash/$size_in_kibibytes/p ";
    done) | \
    sort -n -k1

103472 images/screenshots/signals.png
9434202 video/parasite-intro.avi


git-eradicate (for video/parasite.avi):

git filter-branch -f  --index-filter \
    'git rm --force --cached --ignore-unmatch video/parasite-intro.avi' \
     -- --all
;

rm -Rf .git/refs/original && \
    git reflog expire --expire=now --all && \
    git gc --aggressive && \
    git prune

Note: the second script is designed to remove info from Git completely
(including all info from reflogs). Use with caution.
