20,000 files

I've just found over 20,000 saved files from over a years racing,no idea what they are,pretty sure i don' :ot need them,any one help please in respect of turning something off?

Hi
They are probably old log files. If you set this setting to your preference it should tidy them up:
Settings > Betting Options > Triggers > At the start of the program clear log records older than x days
