Hi Jelena,
If you used BFG and then pull --allow-unrelated-histories, the large files are
again present in the repo. Thanks to delta
compression<https://en.wikipedia.org/wiki/Delta_encoding>, the duplication of
commits itself should not massively increase repository size, though it is not
desirable as it obfuscates the repo history.
You will probably have to use BFG or git filter-branch again to remove the
large files. You could then use git rebase --interactive in order to edit the
commit history to remove any duplicated commits that remain afterwards. I would
advise that this is very likely to produce a lot of merge conflicts. You can
find many guides online on how to rebase.
To remove the files (and commits) from the remote(s) (Github/Bioconductor), you
will then need to force push the "filtered" version of the repository, and to
ensure that all other users with push access to the repositories update all
local copies of the repository to the "filtered" version (eg, using git fetch
origin && git reset --hard origin/master). If you don't do this, the large
files will be added back in when users push to the remote(s).
I would strongly advise that you make a copy of the repository before
attempting any of this, so you can revert to the current version if needed.
Best of luck,
Alan

Dear all,
while trying to fix the WARNING of “too big files” for my repo proBatch, I used
BFG, and ALL my commits (or at least many-many dozens of them) are duplicated
(some up to 5-10 copies). I guess this is because of my pull-push efforts,
which I naively “resolved” with git pull origin master
--allow-unrelated-histories.
What can I do now (because my repo is now massive exactly because everything is
in many-many copies).
Best regards,
Jelena Čuklina.
