FileManager

extension FileManager

Class for handling the operations with file folders.

Original source code from Haneke

  • Calculate the allocated size of a directory and all its contents on the volume.

    As there’s no simple way to get this information from the file system the method has to crawl the entire hierarchy, accumulating the overall sum on the way. The resulting value is roughly equivalent with the amount of bytes that would become available on the volume if the directory would be deleted.

    Note

    There are a couple of oddities that are not taken into account (like symbolic links, meta data of directories, hard links, …).
