To remove untracked files and folders from a Git repository, you can use the git clean command. The git clean command can be used to remove untracked files and directories from the working tree. To remove files interactively or only directories, you can pass additional options.
Here is an example of how to use the command to remove untracked files and directories:
git clean -f -d
The -f option is used to force the deletion, and -d option tells Git to include directories. Note that this will permanently delete the files and directories, so make sure to backup your repository before running this command.
If you want to remove all untracked files and directories including ignored files, you can run:
git clean -f -X -d
The -X option is used to remove only ignored files and directories.
Always make sure to double-check if the files and directories that you intended to remove have been removed by running git status after running the git clean command.
I hope that helps! Let me know if you have any further questions.
