File-sharing can be tricky business, especially on the Microsoft Windows operating system. There are numerous settings to be configured and, even then, you’re not sure if they’ve been configured correctly. Fortunately, Microsoft has found a way to simplify the file-sharing process through the invention of Mesh, part of the Windows Live software series (which now includes Live Writer, Windows Movie Maker, and Photo Gallery).

Mesh is a unique service since, unlike other file-sharing services, it allows you to sync and share files across numerous computers and operating systems. Through this service, you can sync and share files between your PC, a Mac (if you’re one of the lucky ones to own both) and even mobile devices like the Apple iPhone and BlackBerry lines of cellular telephones. You can also share and sync your files with additional devices, if you feel the need to do so.

The service is currently in beta and doesn’t have a lot to offer at the moment (like most new services), but Mesh shows a lot of promise. This could, quite possibly, be the most useful tools for computer users who use several computers (like most computers geeks) or who are constantly traveling and are forced to use a wide variety of computer systems.

How do you keep your files in sync across numerous computers and operating systems? Please leave your thoughts and insights in the comments section below!
