Effective, time-saving software that helps take the strain out of backups.



This program takes care of a different type of file sync; rather than focussing on giving you access to files at the drop of a hat, FreeFileSync lends a hand towards the often laborious process of backing up your computer 4 Free File Sync & Backup Tricks Available In Windows You've heard it a million times: backing up your files is important. Using cloud storage services like Dropbox or OneDrive, you can make a backup for free, without needing to purchase new hardware. Read More .

Its user interface might not be the most appealing, but this sort of backup tool is rarely pretty. The time that could have been spent smoothing off rough edges has instead been put towards ensuring that this program will make sure that your data is safely backed up.

To that end, it can schedule recurring backups, detect when files and folders have been moved or renamed, and even handle multiple jobs running against the same network share. If you’re responsible for backup — either personal or in the office — FreeFileSync is a very powerful tool to have in your arsenal.



Folder sharing application mildly impaired by technical issues.


Sometimes rather than picking and choosing individual files to share between devices, you might simply want to have a shared folder that you can access from different machines. For example, you might use a desktop computer and a laptop equally as much, and want to have access to the same music library on both.

Synkron can do just that, with a minimalist interface that makes the whole process very simple. Just choose your desired folders, and you can either sync them ad hoc or schedule a particular time to perform a sync on a regular basis.

For the most part it works very well, but the program does have a habit of freezing, which can be quite inconvenient if it happens while you’re syncing important files.

Lightweight portable app for file sync and incremental backups.

DirSync Pro

DirSync Pro offers you powerful synchronization and scheduling options wrapped up in a concise, uncluttered user interface. It’s simple enough that anyone who needs to perform a file sync would be able to get their head around it — but it also has sufficient muscle to appeal to the power user.

That makes it particularly effective for anyone performing file sync tasks on multiple machines.

If you take care of a large amount of machines, DirSync Pro is a cut above the rest thanks to the features it can offer without an install — but this is a sturdy, lightweight program that has a lot to offer to just about any user.

    Thanks for the article, Brad. Any suggestions for SugarSync alternatives i.e. selective directory syncing plus cloud/offline capabilities?

      For those of you who are looking for alternatives, I highly recommend KrojamSoft SyncFile. It is the best software I ever used.

    Strongly recommend SyncBack which very powerfully syncs / backs up / mirrors files, folders or drives of choice across a network or even off site. I've happily used SyncBack SE for many years with Windows. Looks like they now have SyncBack Touch which is cross-platform, between Windows, OS X and Android. Haven't tested that.

    I recently helped a coworker set up RoboCopy on a schedule to back up archive-ready files to a USB drive (using Task Scheduler). Robocopy is now built into Windows Vista and 7; it was part of the Windows NT 4.0 Resource Kit.

    Two options for the "DIY" crowd are Bittorrent Sync (for those who just want to do files) and OwnCloud (for those who might like their own personal Google operating system-like experience, i.e. with contacts, calendar, etc.).

    Yeah, I don't recommend downloading Free File Sync. It gave me a nasty virus just a couple of days ago...that insidious snap-do POS. AND, I downloaded it from Sourceforge, and yes, I've notified them. It installed that garbage completely silently in the background without any interaction from me. And I had unchecky AND malwarebytes running in the background and neither caught it.

      virus isn`t fault of software
      I`m using it and found it as good application. If it had cloud sync it could be the best for me.

    For general file syncing across the network I use GoodSync. I have it set to monitor certain folders (Photos, videos, music) on any PC on the network and immediately send a copy to the NAS if it detects a new file.

    For online syncing and backup I use SugarSync. It is like Dropbox et al except it allows me to assign any folder on my system as a "Live" folder to syncing to the cloud. And from the client on any device (PC, tablet, phone) I can select any folder or tree of folders and say "I need access to that folder on this device" and it will create a live copy locally. It is so much more useful and flexible than DropBox, OneDrive etc I really do wonder why people persist with them. Why be forced to keep all of the stuff you need where they want it?
