Synkron Comments

Really good for a sync tool.

Comment by Satuim
about Synkron Oct 2016

I like this as a synchronisation tool.
However it really isn't made for backups, So it really isn't advisable to us it as one.
If however you feel like using it as one, Make sure to set the original location to be "Master" and the backup to be a "Slave" and under your original location set it to "Do not modify contents of this folder"


Nice video review

Disappointing after a while

Negative Comment by drezha
about Synkron and SyncBack Sep 2011

Initially I thought this was a great program, being similar to Syncback but on the Mac. Joy was shortlived. Trying to sync large amounts of data caused it to die. Shame that Syncback SE doesn't have a Mac version as that is the biggest program I miss moving to a Mac.


Synkron V1.6.2: No proxy for "Check for update"

about Synkron Jun 2011

Synkron V1.6.2: You cannot define a proxy for the internet connection:
See Feature Request ID 2947864: .
Everybody, who is using Synkron and has only access to internet by using an proxy, cannot use the "Check for update" feature.
*It is necessary to supply a proxy definition menu, *
as it is realized in the Firefox Addon "Proxy Selector" (see, but additional with a proxy password and with the following 5 options available:

  • No proxy,

  • Auto-detect proxy settings for this network,

  • Use system proxy settings

  • Manual Proxy Configuration with URL, password and Port for a HTTP Proxy,

  • Automatic proxy configuration URL.


Synkron has automatical symmetrical file-deletion 1 Helpful

Positive Comment by em4020
about Synkron and USBAgent, Synchredible, PureSync Jun 2011

In difference to SyncBack free edition Synkron has an automatical file-deletion at the other side (equal which side) of a sync-folder-pair, if file-deletion-time was later than last-file-change-time at the side, where the file still exists.

The advantages of Synkron in comparison with other sync-apps are:

Not very important disadvantages:

  • No (without mouse visible) indication of date, time & size of the files in the two sync-directories, what is usual in all other sync-apps. However: if you move the mouse over "OK" or "OBSOLETE" you see Date and time of the files.

  • relatively long analysis- and syncronization-procedures only with hourglas instead of progress report

  • Difficult to understand terms: OBSOLETE means:
    The files in both directories have a different modification date.
    Better instead of "obsolete" would be "time difference"

  • You cannot call a bat-file after the synchronisation, as this is possible with PureSync or Synchredible.

  • You cannot start a sync, if a USB-stick is detected as you can with Synchredible or USBagent


DirSync Pro is still the winner in my book, but not by much

Comment by NginUS
about Synkron and DirSync Pro Jun 2011

Yeah, this one looks good, has some features I'd find useful, but it doesn't check it's work, and that's a deal-breaker.
No checksummy, no instally.
DirSync Pro is still the winner in my book, but not by much.

Disappointing theres no choice but DirSync Pro & TeraCopy for integrity checking sync/copy tools.
