Problem with Git repository size

Navigation
5

In the company where I work, I was using Git to save a system, where three people use it.

After an image folder has been accidentally sent, making a git pull has become absurd since the downloaded data is almost 1.6GB.

We later removed this folder from images through the file .gitignore . However, even after this change, the repository continues to be very large.

I have some questions to ask about this:

  • How to reduce the size of a Git repository (when an accident occurs as above)?

  • Is there any way to get a git pull or a git fetch , ignoring some files, such as images and / or videos (via parameters or something like that)?

  • Why, even after deleting large files and adding them to .gitignore , is Git still giant? Are ignored (previously added) part of history?

  • And, if "yes" to history, is there any way to delete these unwanted files from history?

Probably what you want is to rewrite the history of your repository, which can be problematic if you do not know what you are doing (I do not know: P). this is done with filter-branch . An example: 

git filter-branch --tree-filter 'rm -rf path/file' HEAD

You may need adaptations, as needed, for this to read the documentation.

You can also delete a commit and make a rebase but I think it would be more complicated.

You can make a cherry-pick and remove or undo a patch .

Here has a good explanation of the cherry-pick and here has a question answered that closely resembles your problem.

I suggest a lot of quiet at this time to not remove anything beyond what is necessary.
