Reduce Repo Size

# Reduce Repository Size

This document describes how to remove old files from Git history to reduce repository size

To remove sensative info (like passwords) follow this [document](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/removing-sensitive-data-from-a-repository).

Check size of the repo by running

`git count-objects -vH`

Install **git-filter-repo** from https://github.com/newren/git-filter-repo/tree/main

```
python3 -m pip install --user git-filter-repo  
git --exect-path  
```

Run analysis of the repository

```
git filter-repo --analyze  
```

If it does not run you will need to [download the file](https://github.com/newren/git-filter-repo/blob/main/git-filter-repo) and mannually add to git path (which can be found by `git --exec-path`)

After runing the `filter-repo --analyze`, you can go and check deleted files by navigating to `head -20 .git/filter-repo/analysis/path-deleted-sizes.txt`

To remove files and folders from the repository 

`git filter-repo --invert-paths --path directory/file_name --force`

To delete completly and emptry repositrory size 

`git reflog expire --expire=now --all && git gc --prune=now --aggressive`

Update remote repositroy by forced pushing the changes

`git push --force`
OR 
`git push --force --mirror`
