Kick ass on both Linux and Windows: definitely a top-100 open source project! Much appreciation to the developer for this great app! :)

Now that the venerable FileSync has mysteriously stopped working on my PC, I am relieved to find FreeFileSync works well for me in similar ways.

I have just discovered your wonderful FreeFileSync software. For years I've been using ViceVersa which runs on Windows. Now I have moved everything to Linux, and searched for a ViceVersa replacement in vain. But the discovery of FreeFileSync changed everything. It's BETTER than ViceVersa!! Out goes ViceVersa and I have yet another native Linux app.

I have tried two other free synchronisation software suites: Synkron (also SourceForge software) and RichCopy (from Microsoft). FreeFileSync is better than both of them for a number of reasons:

1. Intuitive user interface: I setup a multiple folder synchronisation within minutes! The buttons are clear, and if you aren't exactly sure of their function, hovering the mouse over the buttons will reveal clarifying information.

2. Informative: I knew exactly what files were being deleted or updated. The initial "compare" function is MUCH clearer and easier to use than Synkron's "analysis" function. Synkron would give no information about the analysis while it was occurring, so you don't know what progress it is making. FreeFileSync lets you know how the comparison is going, and gives a very handy graph to show progress, including file transfer rates, etc...

3. Stable: I have not yet had FreeFileSync crash on me. RichCopy and Synkron have both crashed, and Synkron tends to freeze the system.

4. Efficient: Synkron writes the synchronisation files to a backup file for some reason which I could not disable in the settings. This both slows the system down, but also uses up a significant amount of hard drive memory over time, since these files are not deleted. Quite simply the best free synchronisation software I have ever used!
