Hi,
is it possible to add application variable for example FBProjectExt which will contain extension of current project file (similar to FBProject or FBProjectDir variables) I know I can to read extension from FBPRoject variable but I need this information in almost every script and it would be nice to have this information as built-in.
best regards
Adam Siwon

I was able to include a FBProjectExt as a system variable inside FinalBuilder 8.
The latest build with these changes can be located here:
