引用 1 楼 zhao4zhong1 的回复:

#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

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.

	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);

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
