Windows 用c++实现，文件路径和目录名的读取保存

要实现如题目所说的功能，只需要理解递归和C++的基本操作就可以实现了。

- 需要微软的Filename Search Functions

- Remarks

-The _findfirst function provides information about the first instance of a file name that matches the file specified in the filespec argument. You can use in filespec any combination of wildcard characters that is supported by the host operating system.

The functions return file information in a _finddata_t structure, which is defined in IO.h. Various functions in the family use many variations on the
*_finddata_t*  structure. The basic *_finddata_t* structure includes the following elements:

unsigned attrib

File attribute.

time_t time_create

Time of file creation (–1L for FAT file systems). This time is stored in UTC format. To convert to the local time, use localtime_s.

time_t time_access

Time of the last file access (–1L for FAT file systems). This time is stored in UTC format. To convert to the local time, use localtime_s.

time_t time_write

Time of the last write to file. This time is stored in UTC format. To convert to the local time, use localtime_s.

_fsize_t size

Length of the file in bytes.

char name[ _MAX_PATH]

Null-terminated name of matched file or directory, without the path.
