Can DOS close an open file?

I'm trying to setup a cron job for my brother that goes out to the web and retrieves an excel file and overwrites the existing copy on his desktop. The problem I'm facing is I have to kill the process (excel.exe) if the file is open while the batch file runs, otherwise, it will create another copy with a 1 or 2 or 3, etc appended to the end of the filename. For example, the correct filename would be myfile.xls and it will create myfile.xls(1). So, I kill the process before it goes out to the web to retrieve the file. This works, but ideally, I would like to close that particular file without killing the process in the event he has other files in open state . . . is this possible?

Spreadsheet::ParseExcel::Simple(3pm)			User Contributed Perl Documentation		      Spreadsheet::ParseExcel::Simple(3pm)

NAME
Spreadsheet::ParseExcel::Simple - A simple interface to Excel data SYNOPSIS
my $xls = Spreadsheet::ParseExcel::Simple->read('spreadsheet.xls'); foreach my $sheet ($xls->sheets) { while ($sheet->has_data) { my @data = $sheet->next_row; } } DESCRIPTION
This provides an abstraction to the Spreadsheet::ParseExcel module for simple reading of values. You simply loop over the sheets, and fetch rows to arrays. For anything more complex, you probably want to use Spreadsheet::ParseExcel directly. BOOK METHODS
read my $xls = Spreadsheet::ParseExcel::Simple->read('spreadsheet.xls'); This opens the spreadsheet specified for you. Returns undef if we cannot read the book. sheets @sheets = $xls->sheets; Each spreadsheet can contain one or more worksheets. This fetches them all back. You can then iterate over them, or jump straight to the one you wish to play with. book my $book = $xls->book; The Spreadsheet::ParseExcel object we are working with. You can use this if you need to manipulate it in ways that this interface doesn't allow. SHEET METHODS
These methods can be called on each sheet returned from $xls->sheets: has_data if ($sheet->has_data) { ... } This lets us know if there are more rows in this sheet that we haven't read yet. This allows us to differentiate between an empty row, and the end of the sheet. next_row my @data = $sheet->next_row; Fetch the next row of data back. sheet my $obj = $sheet->sheet; The underlying Spreadsheet::ParseExcel object for the worksheet. You can use this if you need to manipulate it in ways that this interface doesn't allow (e.g. asking it for the sheet's name). AUTHOR
