Solid as a rock. Previously only DSynchronise was close in terms of reliability (having tried a whole load of free and paid-for software). Super easy to use and runs flawlessly.

FreeFileSync is truly a fantastic program and it is portable too. I have installed it on an USB stick. I had been using Syncback for over 5 years. I found that FreeFileSync is the only open source freeware that can match the paid version of Syncback software in terms of speed in handling folders with huge number of files (up to 30Gb). It runs perfectly in Windows XP SP2. Its web site says FreeFileSync can run in Linux as well. Many thanks to the author Mr. Zenju.

I have worked with Vice Versa and FreeFileSync. There is no comparison. FreeFileSync is one of finest and most important applications ever written. It works perfectly and handles a critically important computer task that too few people do. Vice Versa had at least one fatal flaw that was insurmountable: If folders had to be created on the destination side, they were created in all lower-case, regardless of the case of the source side. Consequently, the subsequent compare always failed. Their tech support was supposedly unaware of the problem, could not resolve it, and eventually avoided further contact.

This has become my favorite file synchronization tool. Even Araxis Merge seems to have lost its appeal. FreeFileSync uses some special undocumented APIs to accelerate folder reads, and it shows! Also, with the ability to use 3rd-party tools like WinMerge or RapidCRC to compare at a click, it's pretty simple to view changes before committing. — Ascend4nt This has become my favorite file synchronization tool.

Far better than other sync tools for my needs. I was looking for something to backup new and updated games from my Steam library (over 200GB) to an external drive so I can uninstall games to free up space and not have to waste bandwidth re-downloading if I want to play them again.



With FreeFileSync, the scan/comparison results are presented well with lots of statistics, there are buttons to filter the results view with a single click, and I can exclude folders in the right-click context menu (sub-folders are not expanded automatically). The interface is kept simple by having certain elements context-based - buttons that don't have any use to your current task/step in the sync process are hidden. I accomplished what I was trying to do quickly and didn't need to refer to the help file.

FreeFileSync has replaced my data backup software (Acronis) with the feature "file-versioning". It allows you to keep a current full backup whilst archiving any changes/deletions. This feature can't be emphasised enough and is more useful than most backup software that starts with a full version and then keeps incremental or differential archive formats.

Does pretty much everything I need to do better than MS Synctoy. I had started off with Synctoy hearing good things until I found out it won't copy files that are in use. Now I'm using FreeFileSync to sync my XBMC database from my media center to my regular PC. It works like a charm. I also use it to keep my music synced across 2 computers (I like having it in both places) as well as my Portable Apps. It reads the changes ridiculously quick, copies files in use, and the interface stays relatively responsive. — webheaded Does pretty much everything I need to do better than MS Synctoy.

I've been using your tool FreeFileSync for maybe 3 years in a private environment on Windows 7 with some Linux networking and I'm happy with its ease of use and reliability.

Thanks so much for Free File Sync (FFS)!!! Following problem has haunted me for years: Now that I have a 64-bit Win7 Pro OS that supports UNC paths up to 32K I thought the problem would be automatically resolved. But no, the dreaded 260 character path limit was STILL HAUNTING ME DAILY.

I think your FreeFileSync application is pretty awesome. I've only recently discovered it as I was looking for a good sync program to use on iMac/OSX Yosemite and found some reviews for it.



Previously I've been using FolderMatch v3.7.0 for PC but it's quite old now and doesn't seem to get much in the way of support/updates. Anyway, since I started using FreeFileSync on my Windows 10 PC and iMac I've been really pleased by the ease of use, performance and features. Really great job!

Outstanding program. And it's free!! I have used this program for about 3-4 years now. And it is simply amazing. I had been looking for a program like this for years. The one I used to have was ViceVersa, until it became too expensive. It basically mirrors my important folders over to my NAS (Sylonogy and D-Link). It does such a great job showing exactly what is going to change (delete/add/modify). It's so simple to use, but also customizable. You can change the behaviour of individual files. Simply the best.

Excellent, works perfectly between my MAC and my corporate server based on a Microsoft environment. The only "bad" point that I see, is the usage of Realtimesync, a tool to automatize the synchronization when a folder becomes available. It's not fully explained how to manage more than one directory! — amaygeoz Excellent, works perfectly between my MAC and my corporate server based on a Microsoft environment.

Awesome!! I have been looking for an application like this for months!! Finally I found something that can efficiently manage all my folders (photos, music, text files, applications, etc.) which I am constantly editing and for which I need to create backups for on my laptop, ipad, 2 external hard drives and virtual hard drives such as icloud, dropbox, google drive, one drive etc.

Best of all!!! No doubt, forget Synctoy. Now 5 years using it on Windows without trouble. — rodob Best of all!!! No doubt, forget Synctoy. Now 5 years using it on Windows without trouble.

Used to use MS synctoy but it's so out of date you can see there is no future in it. Looks like sync center is the way to go for MS native but I have Windows 7 Home so I don't have that choice.



Anyway, came across this, judged it on downloads per week and gave it a go. Really impressed, easy to setup and with just a little reading you can get it to do realtime sync with RealTimeSync that comes with it!



Looks like it's maintained well and kept up to date (big plus) and I like the way it can use Windows Shadow Copy for locked files.

A good sync tool needs reliability, batch capability, a compare-only mode, and configurable rules for dealing with different out-of-sync cases.

I have used a bunch of backup software, some paid and some free. But, Free File Sync is the simplest most straightforward way to back up files. All I did was copy the pertinent directories to a 1.5 TB USB connected drive, then set up a batch file in FFS to run every day at noon and sync the two directories. Like magic it works flawlessly. And, rather than go through some clunky interface to restore something it is a simple as going to the external drive and copying the files back. — Bob in New Hampshire I have used a bunch of backup software, some paid and some free.

I created an account just to post my praise to the author. Class A material. DFS Replication with Windows Server was proving to be a nightmare. Deleting files without reason, failing to replicate in both directions, erroring out, just becoming an overall headache.



This solution was not only intuitive to use, easy to integrate, and easy to confirm functionality (The log files are heaven sent - They are concise and to the point yet in depth and serve a purpose), but is extremely powerful with the configurable batch jobs.

I have been searching (for a long time up to about 2 years ago when I found FreeFileSync) for a utility that does this, even contemplated creating my own. FreeFileSync is a one stop solution that does it all, and does it the way I expect it to. And its versatile and user friendly enough to compare files produced by the engineering tools I use. I've even used it to check disk transfer speed in real life scenarios, works like an absolute charm.

It really became a tool I use extremely often, it's one of my must have's like 7zip. It beats "Unison" hands down for user friendliness and speed to install and get on systems. It beats the tool "Beyond Compare" hands down because it's open source and freely available, but I have to say, I'd love the "Beyond Compare" capabilities, but I cannot justify its cost.

After wasting $40+ dollars on a competitor's product, I tried out freefilesync.

Since I am a backup paranoiac because I have lost data several times, I want something that is quick and painless. This is super easy to use. It also, since it does not give me an error message, copies all the files that a windows copy and paste would not copy because the file names are too long or they are organized in too many sub-folders (what a hassle that is, but that is another windows problem). Have I confirmed this by testing and verify copying? No. It is easy enough to do, but I am way too busy.

Just like people believe in their country and a God, I believe in FreeFileSync. The best part is that you are not spammed with advert pop ups or anything like with other freeware.
