On instaling an Iomega 250Gb network (1Gb) external harddrive I was surprised that it had access to a service called Foldershare.

This is an online service that allows Folders to be sync'd and files accessed remotely from your home PC or device.  Because the Iomega has the FolderShare software built in it just works.

HOWEVER Microsoft found this such a good piece of technology that they have bought it and the service is to terminate.  Presumably some form of Foldershare will appear in MSN Live, however until it does here are some links to other apps that do a similar thing. (None of them seem to rate as highly as FolderShare)

Today, however, there are any number of inexpensive, Web-based applications that let you move files between point A and point B. You can use a remote access tools like Laplink Everywhere or 01 Communique's I'm InTouch. And if you'd like to swap files with friends, family, and colleagues, you can use private peer-to-peer apps like Grouper, Qnext, or ShareDirect. Then there are apps like BeInSync and ByteTaxi's FolderShare. With these tools, you can easily swap files among your own machines and also with friends and family. And you can automatically synchronize files and folders across multiple machines, avoiding manual transfers entirely. If you change a file on one machine, it's automatically changed on all the others.
