Data directory cleanup

[Turtle Trader]

There are tons of small files in the my NinjaTrader Data dsubirectories.

I would like to not carry these forward into my hard drive backups, and I would like to not have unnecessary files on my hard drive....do you have documentation on what these files are and what their purpose is?

Except for when I load Replay data, I don't want to keep any historical data (on my system) beyond what my charts have currently loaded.

I would like to automate a process to delete all unnecessary files.

Or, does this exist in Ninjatrader?

Seem those files increase like rabbits...isn't that eventually going to cause a storage problem?

Thanks
