I tried the Linux version in Ubuntu. I have 32 bit Windows so I couldn't test the Windows version. To run in Linux I had to install Java, which was not hard after a little bit of Google searching led me to

It was not immediately obvious how to do things but after a bit of playing around I figured out how to create archives, open existing archives, add and extract files and test the archive. There are a lot of options which might be confusing to someone unfamiliar with the command line version but were pretty obvious to me. Probably the best thing would be a help screen that explains what the program is supposed to do. Concepts like versioning are probably unfamilar to someone used to zip, 7zip, rar, etc.
I was getting console errors like this when I was resizing the window but it didn't seem to stop the program from working:
Code:
(de.tt.zpaqgui:3598): GLib-CRITICAL **: Source ID 15270 was not found when attempting to remove it
(de.tt.zpaqgui:3598): GLib-CRITICAL **: Source ID 15325 was not found when attempting to remove it
(de.tt.zpaqgui:3598): GLib-CRITICAL **: Source ID 15454 was not found when attempting to remove it
Not all of the features are available through the GUI, like compare, purge, and encrypt. But that's probably OK because a GUI is supposed to make the program easier to use. My inclination would be to have a GUI similar to zip, or that looked like a folder that you could navigate in the usual way without the user being aware that the files are compressed. You could drag files in or out and it would automatically add or extract them. One difference from zip is that the old versions would still be available. To support the full functionality I would need to add commands to zpaq to move or rename files and folders and change their attributes.
But I agree you need a command line version. I run backups from a script and you can't do that with a GUI.
Anyway, thanks for working on this. When it's ready for release I'll add a link on the zpaq home page.
