本人很急，麻烦会弄的大神，给个思路或者指导意见呀

6 个解决方案

#include <stdio.h>

#include <stdlib.h>

char cmdstr[1024];

char d;

char fn[256];

int main() {

 printf("Enter a filename:");fflush(stdout);

 scanf("%[^\n]",fn);

 sprintf(cmdstr,"dir /b /a-d /s \"%c:\\%s\" >d:\\filesinall.txt",'c',fn);

 system(cmdstr);

 for (d='d';d<='z';d++) {

  sprintf(cmdstr,"dir /b /a-d /s \"%c:\\%s\" >>d:\\filesinall.txt",d,fn);

  system(cmdstr);

 }

 system("type d:\\filesinall.txt");

 return 0;

}

你这个不好用啊

可以吗？得是当前路径下的吧？不同文件夹下的文件可以同名的呀

GetFullPathName function
Retrieves the full path and file name of the specified file.
DWORD WINAPI GetFullPathName(
  _In_   LPCTSTR lpFileName,
  _In_   DWORD nBufferLength,
  _Out_  LPTSTR lpBuffer,
  _Out_  LPTSTR *lpFilePart
);
Parameters

lpFileName [in]

    The name of the file.

    This parameter can be a short (the 8.3 form) or long file name. This string can also be a share or volume name.

    In the ANSI version of this function, the name is limited to MAX_PATH characters. To extend this limit to 32,767 wide characters, call the Unicode version of the function and prepend "\\?\" to the path. For more information, see Naming a File.
nBufferLength [in]

    The size of the buffer to receive the null-terminated string for the drive and path, in TCHARs.
lpBuffer [out]

    A pointer to a buffer that receives the null-terminated string for the drive and path.
lpFilePart [out]

    A pointer to a buffer that receives the address (within lpBuffer) of the final file name component in the path.

    This parameter can be NULL.

    If lpBuffer refers to a directory and not a file, lpFilePart receives zero.

#6

	WCHAR buffer[BUFSIZ] = {0}; 

	LPWSTR lpPart[BUFSIZ]={0};


	// Retrieve a full path name for a file.  The file does not need to 

	// exist.

	 GetFullPathName(_T("Big5.dat"),

		BUFSIZ,

		buffer,

		lpPart);
