All too often an interesting item is discovered on a system and everyone wants to know if the item exists on any other system. This could be a daunting task but this can be accomplished using PowerShell. With the location and name of the file in hand, the following can be done:

$computers = list_of_computers
$location = path_to_item 

foreach($comp in $computers)
{
    if(test-path \\$comp\c$\$location)
    {
    $comp
    }
}

Depending on the number of systems, the use of Jobs may be a more suitable option.
