blide question

how do i tell blide to save the open files before compile?

Ive just got in a right mess because i thought the files had saved and well, i think you can guess the rest :(

Never mind, it seems to now ?!?

If you're working with several files, and you want all of them to be saved before you compile or run anything, create a project.
In fact, creating a project is the recomended way to work with several files. The non-project files are there just for little tests and thinks like that.
