It is important to note that L_PreLoadFilters must be called prior to loading, saving or getting information about a file. In addition, L_PreLoadFilters must be called before calling L_IgnoreFilters for L_IgnoreFilters to work properly.

In case the current ignored filters list should be changed, call the L_GetIgnoreFilters function before calling the L_IgnoreFilters function.
