traynotifiershutdownport key in "C:\Users\LoginUserName\.smartbear\com.smartbear.ccollab.client.txt"

Hi

I see in the  "C:\Users\LoginUserName\.smartbear\com.smartbear.ccollab.client.txt"  configuration file

the following key=value pair

 

traynotifiershutdownport=57499

traynotifiershutdownport=-1

 

How can this traynotifiershutdownport=57499 information be used  ?

Perhaps to nicely exit the "C:\Program Files (x86)\Collaborator Client\ccollabtray.exe" application ?
