Notes about the NSE file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The NSE file type is primarily associated with 'Nmap Security Scanner'. The Nmap Scripting Engine allows users to write (and share) simple scripts (using the Lua programming language,) to automate a wide variety of networking tasks.
