It's very simple program which can easily be used in any business without spending much money since it comes free from most companies like Microsoft etc..
Sometimes there are some errors but I just need few minutes then everything works fine again as before! Nothing so far really dislike about this product except maybe its price should also come down because currently too expensive compared with other similar programs out their (like WinRAR). This has been saving us lots of our precious time especially when we have large file sizes around 2GB - 10 GB per day where downloading takes way longer than uploading hence making productivity suffer greatly during these times.
