I want to put the program in the software directory. How should I write the path in cmd?

I tried cmd= "Tools\xxx.exe", "\Tools\xxx.exe", "..\Tools\xxx.exe" it didn't work!

'@app.dir\Tools\xxx.exe' or "@app.dir\\Tools\\xxx.exe' or path.combine(app.dir, 'Tools', 'xxx.exe') - only full path

'@app.dir\Tools\xxx.exe' or "@app.dir\\Tools\\xxx.exe' or path.combine(app.dir, 'Tools', 'xxx.exe') - only full path

thx
