The ever-growing size of hard drives means the need to reduce file sizes when storing data has been reduced, but SDDs still cost significantly more per gigabyte than traditional spinning hard drives, so compressing files can still be very useful.Ĭompression is also very helpful when you want to send several files via email and keep them within the attachment size limit, share them via a service like WeTransfer, or send them to a remote cloud server. With the right file compression software, sharing and archiving files is easy.
