Скачать или смотреть Scratch Utility. Recursive File/Directory Scratching.

The File Manager allows you to scratch individual files, or to recursively scratch whole directory trees.

To accomplish this task, the File Manager prepares a "file scratch job", opens the Scratch Utility and passes it a pointer to the job. Scratch then does the actual work, and loads in the directory shared library to help it accomplish this. Since the File Manager already has the directory shared library loaded in, no additional memory is needed to load it a second time for the Scratch Utility.

More than just being a service Utility for File Manager, ANY C64 OS Application that needs to do a file scratch task (including a recursive scratch which is onerous to code and get right), can simply compose a file scratch job and invoke the system's Scratch Utility.
