    file operations which may run in the background

    CopyCorrupt:

        tries to skip over bad sectors in the input file, by skipping them and

        writing them as zeros. Used for partial recovering of old disks and tapes.

    Erase:

        fill file with zeros (to be really erased from the disk) before removing.

        We use this, if the file contains security relevant data (such as crypto-keys)

    [instance variables:]

        actionForAll .......... a 3-state (true/false/nil) flag, which controls if the current

                                action should be performed for all remaining files

                                (i.e. if deleting, and 'Same for all' was checked, and deletion was confirmed,

                                 the remaining files are also deleted without asking again).

                                If nil, the operation will ask again for the next file.

        result ................ boolean outcome                            

      In Create:        

        createdFile ........... name of created file/directory (name as given by user)
