Hello MichaelAlexander,

You will need to delete some files on your hard drive to free up disk space or you will need to purchase a larger hard drive.

Below is a public link to a helpful article by microsoft about freeing disk space.

This one is about running disk cleanup.

If you have older NinjaTrader backups, you may delete all but the most recent in:

• Documents\NinjaTrader 8 Backup\

You may also try clearing the historical data and market replay data from NinjaTrader in the Tools -> Historical Data Window.
Right-click Historical Data -> select Remove
Right-click Market Replay Data -> select Remove

Any needed historical data will be re-downloaded from your data feed connection, but any older data taking up space that isn't used any longer would be removed.

Hello MichaelAlexander,

The historical data can be removed from within NinjaTrader 8.

• Click Tools -> Historical Data
• Right-click Historical -> select Remove
• Right-click Market Replay -> select Remove

If you have older NinjaTrader backups, you should delete all but the most recent in:

• Documents\NinjaTrader 8 Backup\

Then empty the recycle bin.
