Beep on folder change, windows

22. 10. 2021

Combining total commander, when_changed and mpv.

cd totalcmd # starting dir

In directory next to totalcmd ../util/whenChanged are

play.bat
chime.flac
when_changed.exe

where play.bat is

..\mpv\mpv --no-video turkey.wav

and total commander button is

Command: cmd /K when_changed
Parameters: "%P\**" play.bat
Start path: %COMMANDER_PATH%\..\util\whenChanged\
Icon file: %COMMANDER_PATH%\..\ico\actions\view-media-chart.ico
Tooltip: beep on change

When button is pressed directory monitoring (recursive) is in effect (cmd window will open) and on any changes mpv will play chime.flac.

Update, instead of play.bat there could be playRnd.bat which would play random file from folder

@echo off 
setlocal enableDelayedExpansion

msg.exe /TIME:5 %username% "Stuff changed."
