How does MFC check the number of files in a folder

Use CFileFind

CFileFind filefind;

CString strPath="C:\\";//Indicates the address of the folder to be searched

CString strDoc="*.*";//Indicates the type of file suffix to be searched

CString strFind=strPath+strDoc;

int nFind=0;

BOOL bworking=filefind.FindFile(strFind);

while(bworking)

{

     bworking=filefind,FindNextFile(strFind);

    if(!filefind.IsDots() && !filefind.IsDirectory())//not "." not ".." and not a folder

    {

        nFind++;

    {

}

The final number of nFind is the number of files found.
