Who to delete data from NFA?

Who to delete data from NFA?

Hello!
I have got a problem.

My database has been statistics since 2015. I do not need her. The hard disk is running out of space. I want to give the data, but I can not.
I tried to follow the recommendations from this forum, but I can't. I was able to release only 2 GB out of 40.

C:\ManageEngine\NetFlow\pgsql\data\base =  35GB


  1. C:\ManageEngine\NetFlow\troubleshooting>rawCleanup
    Path : C:\ManageEngine\NetFlow\troubleshooting\..\conf\netflow\nfa.properties
    PortCheckerUtil.getPort : serviceName :WEBSERVER_PORT Flag : false
    C:\ManageEngine\NetFlow\bin\\..\pgsql
    ".\setcommonenv.bat" not internal or external command, executable program or batch file.
