Notes about the LWT 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 LWT file type is primarily associated with 'Lightwright' by John McKernon Software. Lightwright is a cross between a spreadsheet and a database, designed specifically to manage professional lighting design paperwork.
