Open the most recent file in a network drive

Is there any way to perform this operation using the vlc? I already have the code that opens the last recent file in this case a file of both video and audio the mess is as follows: when doing this operation I use pushd since if I use net use generates error:

pushd \192.168.1.100\carpeta
    for /f "tokens=*" %%a in ('dir /b /od') do set newest=%%a

then I pose:

net use  \192.168.1.100\carpeta /delete

or /d or /del and none works, I get errors.
