Videos and MP3s are already compressed so it's unlikely to get any more compression. When you find the files are already compressed then to get this much compression you have to eject some of the files.
I caught a sale on 2TB USB HDDs so my backup copy space went up to that. I was hovering around 500GB so for me this will do for some time.
I recently recovered some data from a 1tb hard drive (thanks to Cnet for this!) and would now like to find a way to compress this data down to maybe 250g or less so that I can store it away in multiple places as an emergency safety net so that I will never lose this data again. Is there software out there that will allow me to do this? I am thinking about something simple such as Winzip or Winrar but for larger files so that if I really need it, I can just unzip the file. Can anyone help me with this please?
