The git repository cannot be deleted

In Git, when we don't need certain files or folders, we usually use the "git rm" command to delete them from the Git repository. But sometimes, we will find that even if we use the "git rm" command, these files cannot be completely deleted from the repository. This is a very frustrating thing, because it will make our Git repository continue to grow and become difficult to manage.

Why does this happen? Mainly because there are multiple branches in the Git repository, some branches may still hold references to these files, in this case, even if we delete these files using the "git rm" command, the Git repository will still keep them citation. These files are not completely deleted and space is not freed.

So, how to completely delete these files from the Git repository? Here are several methods:

Method 1: Forced deletion

This is the simplest method, just use the "git rm -f" command. This command will force the deletion of tracked files and remove all references to them in the repository. But be aware that this method will permanently delete these files and cannot be recovered.

Method 2: Manual deletion

If you do not want to permanently delete these files, or you need to copy these files to other places, you can delete them manually. You can use the command line or graphical interface method to delete the files or folders you want to delete. Once these files are deleted, you can use the "git add" command to record the changes and commit them to the repository. This way, all branches in the Git repository will be updated and references to these files will be removed.

Method Three: Clear Git Cache

Sometimes, even if files are deleted using the "git rm" command, the Git cache will still cache the status of these files. At this time, we need to clear the Git cache and let Git track these files again. The command to clear the Git cache is as follows:

git rm -r --cached .
git add .
git commit -m "Remove files from repository"

This command will clear the status of all files in the Git cache and submit the modifications to the repository. This way, all branches in the Git repository will be updated and references to these files will be removed.

Method 4: Reset the repository

If none of the above methods can completely delete these files, you can try resetting the repository. This method will reset all contents of the repository, including all branches and references, returning the repository to its original state. But be aware that this method will permanently lose all modifications in all repositories, including commits and modification records. You can reset the repository using the following command:

rm -rf .git
git init
git add .
git commit -m "Initial commit"

This command will delete all contents of the repository, including all branches and references, and reinitialize the repository. You can then use the "git add" and "git commit" commands to add new files to the repository.

Based on the above methods, we can completely delete files that are unnecessary and cannot be deleted in the Git repository. However, before performing any operations, be sure to back up your repository to avoid data loss.
