Import a text file by connecting. Select a file by manual.

Hi,

I try to Import a text file by connecting it. Everything working fine. When I open a Excel file it automatically update the excel sheet's from Txt file. I have 5 different txt file and data goes different excel sheets.
But now the problem TXT file name is not always be the same. So I need to select manualy the correct file.
Problem is that I cannot know which txt file I should select, because Excel does not tell it to me. There is some small changes in txt file name, but data have to goes to right sheet.

Any ideas?
