There is only one file type that uses the .LOADERS extension:
GTK+ Loaders File
Program support file used by applications that use GTK+ (the GIMP Toolkit), a framework used for creating multi-platform GUIs; contains data used in the process of loading and updating GTK+ components.
An example application that uses GTK+ LOADERS files is Pidgin, an instant messenging client.
