File synchronization software comes in many shapes and forms. From
cloud storage services that allow you to sync files with the cloud and
from there to your other devices to local solutions that you use without
third-party involvement.
This article concentrates on local solutions only that are offered
for free and run on all supported versions of the Windows operating
system.
While cloud syncing services have their advantages, it makes little
sense to use them when you want to sync files in a local network between
devices.
Before we look at the programs that we reviewed for this article, it
is important to define what makes a good file synchronization software.
Requirements
- Supports manual and automatic (scheduled) modes of operation.
- Supports one-way and two-way synchronization of data.
- Filters to include/exclude files or folders based on rules that you specify.
- Should sync files in use.
- Should work with a variety of devices including internal and external hard drives, network shares and removable devices.
- Should not limit you in regards to the synchronization (no file limits, use limits).

Allway Sync - Limits syncs to 40,000 files per calendar month
Bvckup 2
Bvckup opens a clean interface on launch., First thing you do is create a new backup profile under File and configure it.
There you select the source and destination folders as well as all
parameters for the job. You will notice that you can only configure
one-way sync operations using the program.
What sticks out on the other hand is support for delta-copying files
which reduces the time it takes to update already synced files by
transferring only the parts that have been modified.
The program can monitor the source directory in real-time, using
specific intervals or manually. The preferences hold additional options
of interest. It is for instance possible to link backup jobs to
removable devices so that they are only run when the device is connected
to the system.
The progress is highlighted in steps when a job runs. It highlights
the current operation and the remaining steps and errors so far. A
detailed log file is available as well which you can enable under
options.
Create Synchronicity
Create Synchronicity is an easy to configure file backup and
synchronization software. Compared to other syncing programs it is
rather bare-bones which does not have to be a bad thing depending on
your needs.
It does support one-way and two-way syncing though and a couple of
additional features that you configure during setup of a new sync job.
It supports a preview option that displays exactly what will happen
when you run the synchronization job. There is however no option to make
last minute adjustments to the job which means that you will have to
open the configuration of the job again to do that.
The sync dialog displays all there is to know about the process
including the elapsed time, progress bars, the speed of the process and
how many files and folders were created and deleted so far and how many
are left.

FreeFileSync
Attention: The
program ships with adware. Mystartsearch was offered during test
installations and the only option to skip it was to switch from Basic
(Recommended) to Advanced and remove the checkmark from the Install
Mystartsearch box there before clicking Next.
FreeFileSync's interface leaves you puzzled for a moment where to
begin. It is not really that complicated but a little bit of guidance
would help out a lot.
What you need to do is add folder pairs that you want to sync using
the browse buttons. Once you have added at lest one pair, you use the
compare, filter or synchronize button to start a process.
Both compare and synchronize are configured with a click on the cog
wheel button next to their buttons. Compare for instance compares all
files in both folders based on their size and file time.
Synchronize on the other hand displays the sync methods supported by
the program as well as other sync related preferences that you can
configure there.
Please note that you need to run the program with elevated privileges
as you may get access errors otherwise depending on the folders and
files you select.
Compare loads all files and folders and displays them in the
interface. FreeFileSync higlights which files are only listed in one of
the two directories and displays the total size and file count of the
operation if executed.
Scheduling is not built-in but you can export a job as a batch file
and add it to the Windows Task Scheduler manually to run it regularly on
the system.

SyncBackFree
Setting up a sync job is a two-step process in SyncBackFree. You
create a new profile and the desired synchronization method in the first
step.
Once done, you configure the new sync profile in detail in the second
step. A simple version of the configuration is displayed to you by
default. You can change that to an expert configuration if you prefer
that which displays all available options (and some not available in the
free version).
The expert options leave little to be desired. At the very least, it
is necessary to add two folders to the profile but you can do a lot more
than that.
For instance, it is possible to define detailed compare options that
determine whether files are equal or not based no parameters that you
can adjust in the settings.
Next to that, it is the only program supporting compression and
encryption of files, and ftp servers. Another interesting and unique
feature it offers is a performance estimation for the profile
highlighting settings that may slow down the profile.

SyncFolders
The program is probably the easiest to set up thanks to its
streamlined interface. One you click the new button you are taken to the
configuration screen where you configure all sync related options.
Before you run a sync operation, you may want to run a scan first as
it provides information about the job. It lists files and folders to
synchronize, the total size of the data and errors that it ran into.
A click on errors reveals those while details lists all files and
folders and their status in regards to the other folder. A right-click
on folders or files displays options to override the default rules in
place. You can block files from being synchronized or copied for
instance.

Synchredible
When you first start Synchredible after installation you are taken
directly to the task wizard which you can use to create a first sync
job.
Adding a new sync job is not complicated and every option that you
can select is well explained. It takes seven steps (pages) to set up
your first sync job which can be a bit overwhelming if you never used a
sync software before.
The wizard covers all necessary information on the other hand giving
you full control over the process. Here is a quick rundown of the steps:
- Select the two folders and decide whether subfolders should be included.
- Enable one-way or two-way sync, and decide if you want to synchronize all files or only newer files.
- Add more parameters such as deleting redundant files, ignoring hidden files or folders, or comparing file contents.
- Set up filters to include or exclude files or folders from the operation.
- Set up automatic tasks. Schedule synchronization jobs or configure them to run based on certain conditions or system events.
- Add actions that you want run before or after synchronization.
- Add a name, assign a system wide hotkey for the task, and enable the preview feature.
Jobs can be run manually at any time or only manually if you want
that.Another interesting feature is the program's group option. You can
add multiple jobs to a group to run all jobs of that group in one
operation.
Before you run the first job you may want to check the program's
options first as they list quite a few sync related preferences.
Verification is enabled for instance by default while the saving of
reports is not. You can also mail reports, suppress error messages
during jobs, change the buffer size or disable log file creation.
Sync jobs that run show the progress of the operation in the interface. There is also an option to pause the job.

Synkron
Synkron supports folder synchronizations and multi-syncs. The
difference between the two operations is that a folder sync is keeping
files in sync between two or more folders while multisync syncing
multiple source folders with one destination folder.
Once you have added at least two folders you can hit the analyze button to display information about the current sync status.
All folders not synced currently are listed for synchronization but
you can blacklist files or folders to exclude them from the process.
Advanced options are available as well which you can use to define
additional sync related preferences such as not creating empty folders
or syncing hidden files and folders.
Once you hit sync all files and folders are processed and displayed
to you so that you know exactly where the process is at. There is no
progress bar on the other hand which means that you don't know how long
jobs will take to complete.

Which program is the best?
This comes down to your requirements more than anything else.
Synchredible overall made the best impression as it offers an immense
number of options to set up synchronization jobs on your devices.
SyncFolders is another excellent program. While it may lack certain
features, it makes up for them with its straightforward interface which
is probably the easiest to use.
You cannot go wrong with both of them unless you require a specific feature that one of the programs does not offer.
Update:
SyncBackFree is another excellent program that ships with a couple of
unique features. It is probable the feature-richest program of all
programs mentioned in this article.
If you don't require two-way syncing, then Bvckup may be another
interesting choice. The program supports delta-copying which should
speed up consecutive sync jobs significantly.
