Notes about the LO 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 LO file type is primarily associated with 'GNU Libtool' by GNU Project - Free Software Foundation. GNU libtool is a generic library support script. Libtool hides the complexity of using shared libraries behind a consistent, portable interface.
