递归删除基本文件夹，其中所有内容的修改时间不超过n天

import os
import time

def delete_folder_recursive(folder_path, n_days):
    for root, dirs, files in os.walk(folder_path):
        for file in files:
            file_path = os.path.join(root, file)
            if os.path.isfile(file_path):
                modified_time = os.path.getmtime(file_path)
                current_time = time.time()
                time_diff = current_time - modified_time
                if time_diff <= n_days * 24 * 60 * 60:
                    os.remove(file_path)
        for dir in dirs:
            dir_path = os.path.join(root, dir)
            delete_folder_recursive(dir_path, n_days)
            if not os.listdir(dir_path):
                os.rmdir(dir_path)

# 使用示例
folder_path = "/path/to/folder"
n_days = 7
delete_folder_recursive(folder_path, n_days)
