What is the padlock in Metaeditor?

 

I'm trying to delete an EA in my experts folder so I can backtest it, but when I delete it and replace it with a revised version, MetaTrader somehow has a copy of the old version of my EA, as if it's storing it in memory? Also, I was wondering what this lockpad on the icon is for. Would this be related to the issues I'm having?

Delete it with your terminal, not with windows Explorer. In the Navigator Window, right-click on the EA, then click Delete on the popup menu.
