   I compare with both source tree with diff tool. Most files are the same.
   I did not use git diff because there are too many files. 
   But when git add -A;git commit is don, most files are "added".
   This means git think most files are treated as new.

    I have limited disk space. What happens is my disk quota is full.
    We also have gitblit installed on our Gerrit, which tell us the 
repository size is double.

     I will try your command but it takes some time because the repository 
is quit large.
     Thank you for the help.
