这个代码主要是在根目录或根目录下子文件夹中检索目标文件，可以根据前缀或后缀进行检索，并支持输入多个前缀（前缀间使用分号则表示每个关键词检索一次，使用逗号则表示目标文件前缀需符合所有关键词）。再拷贝到新路径上是支持改名和新建文件夹！(This code is mainly to retrieve the target file in the root directory or folder at the root directory, can be retrieved according to the prefix or suffix, and supports multiple input prefix (using a semicolon between prefix said each keyword retrieval time, use a comma represents the target file prefix must meet all keywords). Copies to the new path to support renaming and new folders!)
