Notes about the GSO 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 GSO file type is primarily associated with 'WinOrganizer or GoldenSection Notes' by The Golden Section Labs. GSO appears to be a general extension used for database files associated with at least two of this author's programs.
