git : a file in the history without commits on it, how to explain it?

I am migrating many svn repositories to many other git repositories. Those svn repos have more than 113000 commits. I end up with very large git repos and I like to shrink them.

I have used a script to find out the largest objects. These objects are not in any branches anymore and I wanted to know to which commit they where related. I could not find any ???

I used the command

git log --pretty=oneline --branches -- my_big_file_full_path

But nothing was returned. Can someone explain me why this file has no associated commits ? If that is really the case how to remove all the files that are not linked to any commits ?

PS : the migration process is quite heavy and I am using bfg (which is fantastic) to remove some known unused folders.

I have finally found the answer in another stackoverflow question Which commit has this blob? using the shell script allowed me to find the commit that modified the big file.

Did you clean the repository after using The BFG? As mentiond in the "Usage" section on the BFG site you should use

$ cd some-big-repo.git
$ git reflog expire --expire=now --all
$ git gc --prune=now --aggressive

to get rid of objects in the repositories that are not part of any commit.
