I use Ubuntu because of the speed, performance & batterylife. So i tried to install an windows applications in Ubuntu. And i was installed Notepad++ Software in Ubuntu from Ubuntu AppStore but i am always facing one problem, actually RUN command in Notepad++ wont't execute in Ubuntu OS platform, uninstalling & re-installing causing the same problem. But the same file can be run through open from the "Saved Folder". Why?

Anyone please provide the solution. Why HTML can't able to open through Notepad++ but only possible from file explorer ?
