Hi Filippos, Tks for your advice. When I was in M$Windows age previously I applied DirectCD, carrying data (most .txt/.doc/.pdf/.jpg etc.) on CD between home and office. The CD worked as a mobile HD. After living in Linux age I used .udf system but not very successfuly. Later it came to the DVD-RAM age. I never try it although I have DVD-RAM burner and DVD-RAM available. Recently I notice that DVD+RW allows adding files. I resume my previously idea applying DVD+RW as mobile HD again instead of upload the files as email attachment and download them again. > but you can't do that.

I think it decompresses the tarball behind the screen, on RAM, as mentioned by Ed Greshko in his late posting. Others noted with tks. B.R. SL
