BEATING DBASE II "DISK IS FULL" MESSAGE by Editor, PC.BUG, June 1987 (How to make space and close important files in dBASE II) If you get "disk is full" message in the middle of a project, don't panic. Type the "list files" command and see what you can delete. After eliminating extra files, your program should save properly. If you still get the "disk is full" message, try typing the "clear" command. You should then be able to quit properly.
