Review by Kelvyn Taylor, Personal Computer World.

Peer-to-peer service that lets you share files and folders on your PC. It is easy to use and offers industrial-strength security control. You can choose whether individual users - added at your invitation - have reader, contributor, editor or senior editor access rights, and you can add and remove people or change their settings at will.

Files can also be accessed by logging in to the Foldershare site. However, as the Foldershare service stores no data, at least one of your peer group's PCs must be running and able to accept incoming connections.

Foldershare is ideal for users who need to share files between different computers, but haven't set up their own network. Clients are authenticated using RSA key certificates before a connection is allowed and file transfers are made using 256bit AES encryption. Incoming ports are only opened for the duration of a transfer.

You might have to tweak some firewall settings to allow incoming connections, but if you use a router with Universal Plug and Play support, Foldershare will try to configure it for you. For sharing files with friends, family or colleagues, Foldershare is the ideal solution.

Note that you can only share files up to 2GB in size. There's a Mac OS X version also available.
