if we load workbook object using stream and generate a tiff of it then FilePath is missing in .tiff.
And if we load workbook object using File Path and generate a tiff of it then FilePath will be print in .tiff.
Sample Code
Not Working Code
Workbook _workbook = new Workbook( File.OpenRead(@“D:\Book1.xlsx”));
_workbook.Save(@“C:\Temp\Book1.tiff”, Aspose.Cells.SaveFormat.Tiff);
Working Code
Workbook _workbook2 = new Workbook(@“D:\Book1.xlsx”);
_workbook2.Save(@“C:\Temp\Book2.tiff”, Aspose.Cells.SaveFormat.Tiff);
We reproduced the issue after an initial test as you mentioned by using template file. We found File path is not printed in the header if we create Workbook object using stream.

If you create Workbook object using stream,please set the file as the following codes:
Workbook _workbook = new Workbook( File.OpenRead(@“D:\Book1.xlsx”));
workbook.FileName =@“D:\Book1.xlsx”;
Though we can get the file name from FileStream, we can not get file name from other types of stream.
So it’s better that you can set it with Workbook.FileName when creating workbook object using stream.
