I would like to reduce the disk space (and backup space and time) used by NT 8.
Is it OK to delete files in NinjaTrader8/db/replay and NinjaTrader8/db/tick from the Windows side (in other words using the Windows Explorer), as opposed to deleting them from within NT? In Tools/Historical Data, it's only possible to delete one node at a time; this would take me forever, as I do have a lot of historical (and market replay) data!
Thanks!
