简单实现文件（夹）的复制、移动、删除、获取大小等操作 复制文件或者目录,复制前后文件完全一样。 删除一个文件或者目录 。 移动文件或者目录,移动前后文件完全一样,如果目标文件夹不存在则创建。 重命名文件或文件夹 。 读取文件或者目录的大小 。 判断一个文件是否存在 。 本地某个目录下的文件列表（不递归） 。 递归目录下的所有文件。 将字符串写入指定文件(当指定的父路径中文件夹不存在时，会最大限度去创建，以保证保存成功！) 获得文件大小(Simple implementation file (folder) copy, move, delete, size and other operations for Copy files or directories, copy files around the same. Delete a file or directory. Moving files or directories, move files around the same, if the target folder does not exist is created. Rename the file or folder. Read the file or directory size. Determine whether a file exists. Local list of files in a directory (not recursive). Recursive directory of all files.
