MF_API int64 MFFileSystem_GetSize ( const char *  pFilename ) Gets the size of a file. Parameters pFilename The name of the file to find the size. Returns The size of the file in bytes. If the file does not exist, MFFileSystem_GetSize returns 0. Remarks If the file does not exist, MFFileSystem_GetSize returns 0, however, a zero length file will also return 0. Use MFFileSystem_Exists to correctly test if a file exists. MFFileSystem_GetSize may also return -1 if the files length is not known, for instance, an endless or unknown length network stream.
