CFileFind::GetLength
Call this member function to get the length of the found file, in bytes.
ULONGLONG GetLength( ) const;
Return Value
The length of the found file, in bytes.
Remarks
You must call FindNextFile at least once before calling GetLength.
GetLength uses the Win32 structure WIN32_FIND_DATA to get and return the value of the file size, in bytes.
Observação
As of MFC 7.0, GetLength supports 64-bit integer types. Previously existing code built with this newer version of the library may result in truncation warnings.
Example
// This code fragment prints out a very verbose directory
// listing for all the files in the root directory on the
// C: drive. After the file's name, each attribute of the
// file is printed, as are the creation, last access, and
// last write times.

BOOL bWorking = finder.FindFile(_T("C:\\*.*"));
