功能特点
- 多格式支持：支持20+种压缩格式，包括zip、tar、gz、bz2、rar、7z、xz等
- 智能递归：自动检测并解压嵌套的压缩文件
- 目录展平：所有文件直接输出到目标目录，不保留原始目录结构
- 冲突处理：自动重命名重复文件
- 哈希去重：通过文件哈希避免重复处理相同文件
- 性能优化：使用队列替代递归，避免栈溢出
- 错误处理：完善的异常捕获和错误提示
使用方法
python unzipper.py 要解压的文件路径 [输出目录]
示例：
python unzipper.py archive.zip ./output
测试建议
- 创建包含多层嵌套压缩的测试文件
- 包含不同压缩格式的文件
- 包含同名文件测试冲突处理
- 包含损坏的文件测试错误处理
这个工具能够满足您对递归解压和目录展平的需求，同时具备完善的错误处理和性能优化。
