You can launch third-party applications before or after making backups.
If you need a third-party application to be used for the task, select the "Launch external applications" item and specify the parameters you need.
Please enter a command to be executed (type in the "Command line" field). You can type a full path to an application with parameters, for example: C:\Windows\system32\calc.exe
You can also specify the waiting settings for this Command line.
The set of parameters to run an external application "before" and "after" performing the task is similar.
