Notes about the GLADE 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 GLADE file type is primarily associated with 'Glade'. Glade is a free user interface builder for GTK+ and GNOME. The user interfaces designed in Glade are saved as XML, and by using the libglade library these can be loaded by applications dynamically as needed.
