You can clear the compiled code of your database in the options area of the Compiler window. In the tools menu, choose compile to open the Compiler dialog. Next, click the expanding button to display the Options area. Then, choose clear to clear the compile code. This will delete all the code of the structure file that was generated on compilation. By clearing your compiled code, it will allow your database methods, project methods, and lost methods to be checked by 4D tools. You could also reduce the size of the structure file by compacting it using 4D tools.
