// status : status of the action (depending of the action) :
// Values are :
// ok : OK !
// filtered : the file / dir is not extracted (filtered by user)
// already_a_directory : the file can not be extracted because a
// directory with the same name already exists
// write_protected : the file can not be extracted because a file
// with the same name already exists and is
// write protected
// newer_exist : the file was not extracted because a newer file exists
// path_creation_fail : the file is not extracted because the folder
