Sync is the best way to transfer files between your Mac, PC, NAS, and even server.

Create your own private cloud. Connect devices and sync files securely without sending them on third-party servers. We don’t limit your speed or storage space: our technology works especially well with huge files.

No storage limits
• Sync as much data as you have on your hard drives.

Automatic camera backup
• Sync will back up photos and videos as soon as you take them.
• You can then delete photos from your phone and save space.

Direct transfers, no cloud
• Your information is never stored on servers in the cloud, so nobody can access it without your permission.
• Transfer files directly and fast using peer-to-peer technology (p2p).

Any device and platform
• Access folders and upload files to your tablet, PC, Mac, NAS, and even server.

Supports all file types
• Add photos, videos, music, docs, and PDFs from other apps to any of your synced folders.

Save space
• Selective Sync lets you save only the files you need.

To get the best performance and to avoid running up your data charges while syncing folders, we recommend leaving the "Use Cellular Data" setting off.

Awesome personal cloud, needs alphabetical sort

When my previous solution for keeping critical files synced between computers stopped being supported, I tried a lot of alternatives. Resilio Sync is by far the best solution, provided the devices you want to sync are on at the same time. They have apps for some NAS platforms, too, so now I have my own private cloud.

The iOS app loses a star because it can’t do alphabetical sort: separating out folders should be a configurable option, not a requirement. It’s a real pain to have to check 2 different locations in a sorted list of several hundred items just because I don’t know if it’s a single file or a group of files in a folder. The whole point of an alphabetical sort is to alphabetize things so I can find them by name. If I wanted to sort by kind, I’d sort by kind.

Awesome way to sync files!

This app is a great high speed way to sync files to/from a home PC. I use it for camera backup and now also downloading videos from my PC to my Phone. All at Wi-Fi speeds in the house, but also works remotely. One star taken off because the syncing engine gets confused and usually tells me there a number of files left to sync and never completes. I don’t think it’s real. All files backed up.

Great tool

Best way to sync files between devices. Once setup (setup? What setup?), Just put stuff in it and all device have a copy. For example, I have a folder on my PC called Mobile. In it I have sub folder called Travel. In it I have sub folder call 2017 China trip. I put stuff such as itinery, hotel reservation, etc in the folder and all files will be synced to my wife's phone, my phone and my PC. Can't be any easier.
