File sharing tool BitTorrent Sync has been updated to version 2.0 with a new $40/ year PRO version.

Sync 2.0 introduces the “personal identity”, which automatically gives access to every added folder on all of your linked devices (sync a folder anywhere, and it’s immediately available everywhere else).

“Sync on-demand” acts like a simple remote access tool, allowing you to browse folders on other devices – even if they’re not fully synced yet – and fetch whatever you need. This is a PRO-only feature on the desktop builds, but fortunately mobile users get it for free.

Tweak access permissions in a click or two

Sync 2.0 PRO also provides a “Sync All” option to synchronise all your folders with a NAS, as well as the ability to change or revoke access permissions on the fly (no more disconnect, tweak, reconnect).

PRO users also get enhanced technical support, guaranteeing a reply within 24 hours.

If that’s not quite enough to persuade you to upgrade, there is one other reason: the desktop Sync FREE is now limited to syncing 10 folders at a time. (As before, the mobile clients don’t have this restriction.)

Whichever version you get, BitTorrent Sync 2.0 provides fast file transfer speeds from device to device, with no folder size limits. Folder number restrictions or not, it’s still an interesting alternative to the cloud.
