Also look at FileGetAttr.

//---------------------------------------------------------------------------
long __fastcall GetFileSize(const AnsiString FileName)
{
TSearchRec SearchRec;
long returnValue=-1;

if(FindFirst(ExpandFileName(FileName), faAnyFile, SearchRec)==0)
returnValue=SearchRec.Size;
FindClose(SearchRec);

return returnValue;

}

You can use a int64 type variable instead of a long to support files that are gigabytes in size.

This is how I do it.

hFileHandle = (void*)FileOpen("D:\\File.txt", fmOpenRead );
iFileSize = GetFileSize(hFileHandle, NULL);
FileClose((int)hFileHandle);

I had this program so I just copied
long FileSize (FILE *stream)
{
long length, curpos;
fseek (stream, 0L, SEEK_END);
length = ftell(stream);
fseek (stream, 0L, SEEK_SET);
return length;
}
//----------------------------------------------------------
void __fastcall TForm1::Button1Click(TObject *Sender)
{
FILE *handle;
AnsiString Nombre = FileListBox1->FileName;
AnsiString Tamanio;
handle = fopen(Nombre.c_str(), "r"
Tamanio = AnsiString (FileSize (handle));
Nombre = StrCat (Tamanio.c_str(), " Bytes"
Label1->Caption = Nombre.c_str();
fclose(handle);
}
I hope it help you

A lot of different methods, but mind that in some cases the file can be located on a network. Without read rights it is not possible to open the file.
In those cases you will need FileGetAttr
