Hi Baskar,
why do you need this? You can better select in NWA the selection of logs that you need and then download the data from there. You can also download the entire log if you wish. In my opinion better than dealing with the rolling multiple files of the folder on the server.
I don't know the directory by heart, but search the forum a bit or ask your PI basis guy and you will find the location soon enough.
Regards,
Jörg
