This article provides an in-depth exploration of multiple methods to restore deleted folders in the Git version control system. When folder contents are accidentally deleted, whether in uncommitted local changes or as part of historical commits, there are corresponding recovery strategies. The analysis begins by explaining why git pull does not restore files, then systematically introduces solutions for two main scenarios: for uncommitted deletions, use git checkout or combine it with git reset; for deletions in historical commits, locate the deleting commit via git rev-list and restore from the previous version using git checkout. Each method includes detailed code examples and context-specific guidance, helping developers choose the most appropriate recovery strategy based on their situation.

This article thoroughly examines a common yet perplexing issue in Git distributed version control systems: when executing the git pull command, the repository status displays "Already up-to-date," but the actual files in the working directory remain unsynchronized. Through analysis of a typical three-repository workflow scenario (bare repo as central storage, dev repo for modifications and testing, prod repo for script execution), the article reveals that the root cause lies in the desynchronization between the local repository's remote-tracking branches and the actual state of the remote repository. The article elaborates on the core differences between git fetch and git pull, highlights the resolution principle of the combined commands git fetch --all and git reset --hard origin/master, and provides complete operational steps and precautions. Additionally, it discusses other potential solutions and preventive measures to help developers fundamentally understand and avoid such issues.
