### - (`Hash`) MapFilesToString

Writes file using the .backup.file_append SCR agent. This file is accepted by backup_archive.pl script. Used global variables: selected_files, backup_files.

“sel_files” (integer - number of selected files), "sel_packages" (integer: number of selected packages), "ret_file_list_stored" (boolean: whether the filelist has been completely stored)

Returns:

- (`Hash`) —

  with keys
