My program? It's commandline based. However there's ways to use it. You can either use a batch file.
OR, you can drag the files you are interested over the exe file (
selecting it to run) and it will process them.
You can also rename it to
'nif_tx_local.exe', (
or if the exe is hidden, ignore it). That will give it an automatic option to scan all the files in the current directory.
