BitTorrent Inc. has just released version 1.4 of its Sync application. The new release has a completely redesigned interface and allows users to share files and folders via https links instead of encryption keys.

There are dozens of sync and backup services available on the Internet, but most have a major drawback. They require people to store data on external cloud-based servers that are not under their control.

BitTorrent Sync is a lightweight backup tool that eliminates this drawback, and it’s much faster too.

The functionality of the Sync application is comparable to most cloud-based sync tools, except for the fact that there’s no cloud involved. Users simply share their files across their own devices, or the devices of people they share files with.

Since its launch the application has built a steady user base of millions of users who already transferred a mind-boggling amount of data.

“Since the initial Alpha launch of Sync a little over a year ago, we’ve now hit over 10 million total user installs and have transferred over 80 Petabytes of data,” BitTorrent Inc’s Erik Pounds notes.

Today marks another big step in the development of Sync. With the release of version 1.4 users are now able to share files and folders more easily, by simply sending someone a URL. Previously, people had to exchange encryption keys which seemed more complicated.

People who receive a Sync URL will be directed to a download page where they are prompted to install Sync, if it isn’t already, and start downloading files right away.

Sync offers a wide variety of sharing options. Users have complete control over where their data is going and how it is used. This includes setting read/write permissions and the option to give access to approved devices only.

“Sync gives you full ownership over your data. With no third parties involved in storing or arbitrating your data, you know exactly where your files go,” Pounds explains.

In addition to the easier sharing options and various other improvements, the latest release also has a completely redesigned interface.

For those who are interested, the latest version of BitTorrent Sync is now available for download here, completely free of charge.
