As a simple example for Windows, here's a setup that will copy an encoded file created by kmttg encode step to an iTunes folder:
Create a C:\kmttg\copy.bat script with following contents:
@echo off
copy "%~f1" "G:\Music\Automatically Add to iTunes\"
In kmttg config->Programs custom command set it as follows:
C:\kmttg\copy.bat [encodeFile]
Equivalent of above for Mac or Linux would be something like:
Create an /Applications/kmttg/iTunes_copy.sh bash script with following contents:
#!/bin/bash
cp "${1}" "/Users/myMac/Music/iTunes/iTunes Media/Automatically Add to iTunes.localized"
Give execute permissions to the script:
chmod +x /Applications/kmttg/iTunes_copy.sh
In kmttg config->Programs custom command set it as follows:
/Applications/kmttg/iTunes_copy.sh [encodeFile]
