What might cause workspace to get lost?

[MatthewLesko]

Sometimes when I reopen NinjaTrader, my workspaces are gone and it's back to opening that Default futures workspace that looks like this. What might cause this? I can't seem to re-create it it's just random.

Hello,

If the file is simply missing, the only thing that could cause this would be another program running on your PC that is altering/deleting files on your machine. Though rare, some PC cleaner or space optimizing software will remove files automatically on your machine and it can isolate certain NT files such as workspace files for removal.

I've also linked below to how to recover workspaces that are lost below for reference:
