// $p_add_dir : A path to add before the real path of the archived file,

[256] Fix | Delete

// in order to have it memorized in the archive.

[257] Fix | Delete

// $p_remove_dir : A path to remove from the real path of the file to archive,

[258] Fix | Delete

// in order to have a shorter path memorized in the archive.

[259] Fix | Delete

// When $p_add_dir and $p_remove_dir are set, $p_remove_dir
