SYNCING.NET FileSharing Edition: Private Folder Sync Between Your Devices, With No Cloud Copy
SYNCING.NET FileSharing Edition is a peer-to-peer file sync program from $49.99 a year (3 devices) for Windows, with Mac, Linux, iOS and Android clients. It keeps chosen folders identical across your devices or a small group, and the files stay on those devices instead of a cloud service. It doesn't touch Outlook.
It's for the folder you don't want on someone else's server: client contracts, HR files, a project that's under NDA. You pick the folder, invite the devices or people, and any change on one copy reaches the others directly, encrypted.

Before you buy: it's not free, and it needs two devices awake
Free tools exist for plain device-to-device sync, so the $49.99 buys you the invitation-based groups, encryption and support. And because the devices talk directly, a change only moves when at least two of them are online together, unless you enable the limited Store and Forward queue described below.

Overview
SYNCING.NET started as an Outlook sync tool, and FileSharing Edition is that product with the Outlook side removed and the price cut. Buildway Technology LP develops it now and still signs and ships updated builds; the vendor says a new version comes roughly every two to three months.
You create a Sync Folder, which can be any folder on a local or removable disk, and say who shares it. Everyone who joins gets a full copy on their own device, in whatever location they choose. From then on each edit, new file or deletion is applied on the other devices, and only the changed part of a file is sent.
The vendor's device mock-up: the SYNCING.NET window on Windows browsing a Sync Folder of images and PDFs, with the same folder open in the tablet and phone apps.
Features
Files stay on your own devices
SYNCING.NET FileSharing Edition keeps your files on the devices in the group, with no online storage account to fill up or pay for by the gigabyte. Its server holds account and folder settings, not your files, unless you turn on Store and Forward.
Closed groups by invitation
SYNCING.NET FileSharing Edition lets only the creator of a Sync Folder add or remove members. You can give executives one folder and an outside consultant another, and neither sees the other's data.
Delta sync in the background
SYNCING.NET FileSharing Edition sends just the changed part of a file, not the whole thing, so edits to a large file move quickly after the first copy. Work done offline is kept and goes out when you reconnect.
Mobile and cross-platform clients
SYNCING.NET has desktop clients for Windows, Mac and Linux, and iOS and Android apps. The 2026 mobile updates added Smart Download, which fetches a file only when you open it, and editing of Word, Excel and text files in other apps with the changes synced back.
Store and Forward for devices that aren't on together
SYNCING.NET FileSharing Edition can leave encrypted changes on the vendor's server for a device that's offline. The queue holds up to 500 MB per computer and 50 MB per file, is emptied on download, and expires after 7 days.
Benefits
- No storage quota. The only limit on what you sync is the disks you already own.
- Fewer places for your data to leak from. There's no third-party copy of your files sitting in someone's data center.
- Nothing to host. You don't have to keep a NAS or file server running to get shared folders between sites.
Real-World Uses
- Office and home PC. The folder you worked on at your desk is on the home PC when you get back.
- A small firm sharing case files that can't go on a public cloud under its confidentiality terms.
- Photographers or designers sending large working files to a partner without paying for cloud storage.
- Phone access to a work folder, using the mobile app to open only the files you need.
Who It's For, and Who Should Skip It
It's for individuals and small groups who want folders mirrored between devices and don't want those files on a cloud service.
Skip it if:
- you need Outlook mail or calendars synced. That's the Personal or Business Edition.
- you need a folder on a NAS or network share to sync. Only local and removable disks can be used.
- your devices are rarely online at the same time and you change more than the 500 MB queue can hold. A cloud drive suits you better.
- you're happy with OneDrive, Dropbox or Google Drive. They include version history and web access that peer-to-peer can't offer.
- you rely on Linux. That client dates from 2016.
Usage Guide
- Install on the first PC by running SYNCING.NET.exe (8.4 MB) and creating a user account.
- Create a Sync Folder by picking a folder on a local or removable disk. You can set a maximum folder size.
- Invite your other devices or people. On each device, install the client, sign in, accept the invitation and choose where the folder goes.
- Leave both devices on for the first copy. Later updates only move changes.
- Turn on Store and Forward under Configuration, Options, General Settings if your devices don't overlap.
- Enter your license key before the 14-day trial ends.
Where it falls short
- Open files are skipped until the program holding them closes them, which can catch out database and mailbox files.
- Internet required even on one network. Data takes the LAN when it can, but each PC must reach the SYNCING.NET service.
- Stated limits vary. The vendor's shop page mentions up to 20 PCs in one place, while the sold licenses stop at 10; plan on 10.
- Windows support list stops at Windows 10 on the product page. Windows 11 isn't named, so try it on your PC first.
- No version history is advertised. Deleted files go to the Recycle Bin on each device, and that's the safety net to count on.
What Users Say
We found almost no public feedback on this edition. AlternativeTo has one comment on SYNCING.NET as a whole, from user medalark88 in October 2010: "I like the fact that it syncs over the internet but does not store it in online anywhere." That user passed on it over per-PC licensing. The App Store listing shows too few ratings for a score, so the 14-day trial is your best guide.
Comparisons
FileSharing Edition vs a cloud drive
OneDrive, Dropbox and Google Drive keep a copy online, so your other devices can catch up at any time, and they add web access and file history. SYNCING.NET FileSharing Edition keeps files only on your devices, has no storage limit, and needs devices online together (or the small Store and Forward queue).
FileSharing Edition vs Personal Edition
Personal Edition costs $59.99 a year for 2 PCs and adds Outlook sync, but stops at 3 PCs. FileSharing Edition is cheaper per device and goes to 10, without Outlook.

FAQs
What happens to my files if I cancel SYNCING.NET FileSharing?
SYNCING.NET licenses expire one year after your last payment if you cancel. Your files stay in place on each device, since they were local all along.
Does SYNCING.NET FileSharing use my phone's storage for every file?
No. SYNCING.NET's mobile apps have Smart Download, which fetches files only when you need them and can free the space again afterwards.
Can I use SYNCING.NET FileSharing with a USB drive?
Yes. SYNCING.NET accepts folders on removable drives as Sync Folders as well as local hard disks.
Is the free SYNCING.NET mobile app enough on its own?
The free mobile edition syncs up to 2 GB between your own devices. Sharing with other SYNCING.NET users on a phone needs the mobile Business Edition.
Does SYNCING.NET FileSharing work over the internet between two offices?
Yes. SYNCING.NET connects the devices directly over the internet wherever they are, and works through proxy servers.
System Requirements
- Windows 10, 8, 7, Vista or XP (32- or 64-bit), or Windows Server 2003, 2008 or 2012
- Pentium-class CPU, 800 MHz or faster; 256 MB RAM (512 MB or more recommended)
- Microsoft .NET Framework 2.0 or later
- Internet access (broadband recommended)
Conclusion
SYNCING.NET FileSharing Edition is worth $49.99 a year if you want private folders mirrored across a few devices and would rather not hand them to a cloud provider. The one reason to buy it: invitation-only, encrypted sync with no storage cap and no copy on anyone else's servers. The main reason not to: devices must overlap online, and it can't reach NAS drives, so a cloud drive is simpler if privacy isn't your main concern.
