You can add items under MacOrganize's Tool menu by building code resources and placing them into the 'MacOrganize Tools' folder. You must have at least two resources 'proc' id 128 and 'SCAN' id 128. If you want to filter out files for the Standard File dialog you must provide a 'FLTR' id 128 too. There is a template in the resource files to configure the 'SCAN' resource. Scan type must be 1, otherwise you code will not be executed. If nested folders if true your procedure will be called for all folders and files, contained in the selected directory and subdirectories, otherwise you will called only for the files and folders in the that directory.
