Netflow Analyzer directory structure and backups

I just inherited a NetFlow Analyzer installation that is running out of space. The long term solution is more HD space, but in the short term, I would like to move some data to a different HD.

I see recent data (data & mysql) existing in 2 locations:
D:\NetFlow
D:\AdventNet\ME\NetFlow\backups

The D:\NetFlow data seems to be current, while the other data (D:\AdventNet...) is timed stamped as of 0120 this morning.

I would like to move the AdventNet directory to a separate HD.

Is this backup process part of NetFlow Analyzer, or do I need to look for some other process? If it is NetFlow, where can I change the configuration/location of the destination directory?
