10 years agoIf you dont have it in a revision control tool or made a backup manually yourself, then you will have to manually add them again.
You might be better off copying the lines that include the source files to the project into a .qip file and then just add the .qip file to the project instead, although this will mean you need to control the adding/removing of files via a text editor and not the gui.
