Here is another really cool and fairly secure way to share files and or content with people you choose. Or even just access your own files whilst away. It is called Opera Unite. It is actually built into the Opera Web Browser!
But to just share some files with co-workers, family or friends Opera Unite looks really cool. And some might find it simpler.
With Opera Unite, your friends view the content that is sitting on your computer. You can stream music or video or share actual files. Since this is a ‘live’ connection to your system you will be using internet bandwidth; this may be a consideration if your ISP has very low limits. Also since it is a live connection to your system you should consider all the security implications.
To run Opera Unite applications (File Sharing, Photo Sharing, Media Player etc.), you need an Opera browser version 10.10 or later from http://www.opera.com and an Opera account.
To view or access most of your applications, your friends can use any browser.
Operating systems: You can use those supported by the Opera browser; Windows, Mac, or UNIX/Linux.
To get started with Opera Unite, you just need to install an Opera browser version 10.10 or later, start an application, and then you can begin sharing and collaborating.
Opera Unite applications make it quick and easy to share content. There is no need to upload anything; you share the content sitting on your computer. And, you do not need to configure anything else, such as DNS services or complex access controls. For example, you can install the Media Player application on your home computer for your favorite songs. When you get to work, you can visit your Media Player application and listen to the songs directly from your home computer. No download, no fuss.
How Opera Unite is different to traditional data sharing
With more traditional content sharing, you have to upload the content you want to share, and this is then stored on a central, third-party server, out of your control. Your friends access this stored content from the third-party server.
Enable Opera Unite
To enable Opera Unite for the first time:
From the menu, select "Enable Opera Unite". A welcome dialog displays.
To use Opera Unite, you need to have an Opera account. This is an account that you use for My Opera, Dev Opera (Opera’s developer-community resource site), or Opera Link. Your existing username cannot contain any symbols or spaces to work with Opera Unite.
If you already have an Opera account that does not contain symbols or spaces, select "I already have an account", if necessary, and type your existing username and password. Go to step 4.
If you do not have an account, or have one that contains symbols or spaces, select "I do not have an account", if necessary, and complete your details to create one.
Choose a unique and easy-to-remember username without any symbols or spaces. The username will become part of the link (Web address) for your Opera Unite applications, which your friends will use to access your content or communicate with you.
Select "Show" to read the terms and conditions, and check the box to indicate that you agree with them.
Choose a computer name from the drop-down menu. This name identifies the computer you are using, to distinguish it from other computers you may use. It also becomes part of the link for your Opera Unite applications. Choose an option that best describes how you use your computer, or write your own.
In the panel at the left, highlight an application that you want to use, and select the Start button at the top of the panel. The application start
