Feature request: unzip archives on server

**is your feature request related to a problem? Please describe.**
I'd like to use cpp to access zipped archives of backups and unzip them on the server, instead of downloading the archive and uploading the unzipped one again.

**Describe the idea / solution you'd like**
Ability to unzip an archive

**Describe any alternatives you've considered**
download - unzip - upload

Thanks for considering!

查看服务器的文件处理代码，可能位于处理上传或压缩包的模块中。检查是否已有 zip 处理逻辑或外部库的使用。此功能需要添加服务器端解压功能，可能通过 Python 的 zipfile 模块实现。创建一个 ZIP 压缩包进行测试，并验证服务器无需经过下载-上传往返即可将其解压。
