ExcelLink "ToFileName"

Getting files:

In[2]:=  f = ToFileName[{ExcelDirectory["Link"], "Examples"}, "Stocks.xls"]
Out[2]= C:\Documents and Settings\Anton\Application Data\Mathematica\Applications\ExcelLink\Examples\Stocks.xls

My file on my computer is “This PC\Documents\FRB Forms\14A\2015 Params”

This workbook has 6 spreadsheets. Do i need to include one?

What is the goal? Importing from these files? Performing arithmetic with the resulting matrix?

Yes, to import workbook and work with spreadsheets it contains. The workbook has 6 sheets with about 1100 cells per sheet. I am planning to make a template which work on all of the cells with a specific model to each..
