If you are used to travel I am sure you have been in a situation where you needed a file or to run a program on your home (or office) coputer, but couldn’t, because you were nowhere near it. Of course you can do a lot to prevent this, but the easiest solution (if you ask me) is to install a remote desktop program on your PC so you can access it from anywhere. Now, much remote access software out there that claim to do this (even some free ones). But when it comes to web based remote access to a computer outside of your network efficiency and security should play a major role when deciding what software to use. I’m not saying this is the only trustworthy software, but GoToMyPC by Citrix is one of the most respectet and stabil services and it has been available since 1997.
Also, it costs only 20$ a month and you can even sign up for a free 30 days trial! so, check it out!
