Hi, yunchen
I'm on a business trip recently. Can you see what the problem is?

@Hauptsatana Can you Provide you sample code?
I tried to reproduce what you said with the following code and did not found the .tmp file generated.And I showd windows hidden files and system files.

public void ReadExcel()
{
    using (var file = new FileStream(@"template.xlsx", FileMode.Open, FileAccess.Read))
    {
        var excel = new XSSFWorkbook(file);
        var cell = excel.GetSheetAt(0).GetRow(0).GetCell(0);
        Console.WriteLine(cell.NumericCellValue);
    }

    using (var file = new FileStream(@"template.xls", FileMode.Open, FileAccess.Read))
    {
        var excel = new HSSFWorkbook(file);
        var cell = excel.GetSheetAt(0).GetRow(1).GetCell(2);
        Console.WriteLine(cell.NumericCellValue);
    }
}

@baiyunchen here is code that I used

string filePath = "template.xlsx";
IWorkbook workbook = WorkbookFactory.Create(filePath);
...
workbook.Close()

Tests have shown that .tmp file is produced after workbook.Close() when workbook was opened using string filePath.
If I use FileStream as in your example or exclude workbook.Close() then no .tmp file is generated.

@Hauptsatana It's a bug.
Please reference #35.
