Mistery Path N:1\ versus Y:\

In one of my pc where I have several units C:, D:, E: F: , Y: , Z: , etc

the unit Y: is known inside the options in the windows firewall by N:1\

so in the exceptions figure :

N:1\PORTABLES\PortableApp.com Suite\PortableApps\FileZillaPortable\FileZillaPortable.exe
N:1\PORTABLES\Navegadores . Internet . Correo\Simple Port Forwarding\Simple Port Forwarding\spf.exe
N:1\DittoPrg\Ditto.exe
etc.

What this ?
In other of my pc is simply Y:\
