是mp3好还是wma好(mp3转换wma音质提高吗)

1、不写程序。 用dir *.mp3 /s >>a.txt dir *.wma /s >>b.txt copy a.txt+b.txt c.txt2、用一个MP3播放程序加入整个U盘的目录，再导出。 3、用c++写程序。给你个例子 #include <windows.h>typedef BOOL (WINAPI *EnumerateFunc) (LPCSTR lpFileOrPath, void* pUserData);void doFileEnumeration(LPSTR lpPath, BOOL bRecursion, BOOL bEnumFiles, EnumerateFunc pFunc, void* pUserData)
{ static BOOL s_bUserBreak = FALSE;try{//-------------------------------------------------------------------------
if(s_bUserBreak) return;
int len = strlen(lpPath);
if(lpPath==NULL || len<=0) return;
//NotifySys(NRS_DO_EVENTS, 0,0);
char path[MAX_PATH];
strcpy(path, lpPath);
if(lpPath[len-1] != '\\') strcat(path, "\\");
strcat(path, "*");
WIN32_FIND_DATA fd;
HANDLE hFindFile = FindFirstFile(path, &fd);
if(hFindFile == INVALID_HANDLE_VALUE){::FindClose(hFindFile); return;}
char tempPath[MAX_PATH]; BOOL bUserReture=TRUE; BOOL bIsDirectory;
BOOL bFinish = FALSE;
while(!bFinish){strcpy(tempPath, lpPath);
if(lpPath[len-1] != '\\') strcat(tempPath, "\\");
strcat(tempPath, fd.cFileName);
bIsDirectory = ((fd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) != 0);
if( bIsDirectory
&& (strcmp(fd.cFileName, ".")==0 || strcmp(fd.cFileName, "..")==0)){bFinish = (FindNextFile(hFindFile, &fd) == FALSE);continue;}
if(pFunc && bEnumFiles!=bIsDirectory){bUserReture = pFunc(tempPath, pUserData);
if(bUserReture==FALSE){s_bUserBreak = TRUE; ::FindClose(hFindFile); return;}}
//NotifySys(NRS_DO_EVENTS, 0,0);
if(bIsDirectory && bRecursion) //是子目录{doFileEnumeration(tempPath, bRecursion, bEnumFiles, pFunc, pUserData);}
bFinish = (FindNextFile(hFindFile, &fd) == FALSE);}
::FindClose(hFindFile);
//-------------------------------------------------------------------------
