QuestionTime of reading text file Pin

Hi, I wrote a program in Windows CE platform, CPU is ARM 427MHZ.
when program read a text file(size about 700KB,1000 lines) in Flash memory, it needs about 25 seconds to load the file.

is there a means to decrease the reading time?

C++
file.Open(fileName,CFile::typeBinary | CFile::modeRead);
while ( UNReadString(&file,strLine) ) {
		//strLine.TrimLeft(); TrimRight(); N
		strLine.Trim();
		
		strNum  = strLine.Tokenize(TEXT("\t"),tokenPos);	
		strEng = strLine.Tokenize(TEXT("\t"),tokenPos);	//Get English text
		strCh  = strLine.Tokenize(TEXT("\t"),tokenPos);	
		strRus = strLine.Tokenize(TEXT("\t"),tokenPos);
                
        handleStr();
        tokenPos = 0;
}

BOOL UNReadString(CFile *iFile, CString &strReturn)
{
	TCHAR tc;
	CString strBuff = _T("");
	strReturn = _T("");

	while( ( sizeof(TCHAR) ) == ( iFile->Read(&tc, sizeof(TCHAR))) ) //EOF reached?
	{
		strBuff = tc;

		if(_T("\n") != strBuff) {
			strReturn += strBuff;
		}
		else {
			return TRUE;	//Reached "\n", 1 line added to strReturn
		}
	}
	return FALSE;
}
