Question

我的问题是：为什么我的输出给了我“recycle.bin”文件，而这一切都没有，就像它不会是那里的任何文件（“C：\ *”/“D：\ * “）在我调用FindNextFile（）后，我得到错误18（目录中没有更多文件），问题是，这是错误的

bool data_confersion(PWIN32_FIND_DATAW pFileData, P_SINGLE_FILE pFile){

    //file sieze determining 
    pFile->filesize = pFileData->nFileSizeLow;
    ((int*)&pFile->filesize)[1] = pFileData->nFileSizeHigh;

    pFile->attributes = pFileData->dwFileAttributes;

Answer 1

您的t字符串很可能是错误的。它基本上是logicalDrives（复数），附加了一个*。这不太可能是正确的。

FindNextFile（...）不要“看”文件WINAPI
