How do I repair incomplete files with the par2 parity files ?

With the parchive package ( or par2 package if you use Debian/Ubuntu )and the par2 command :

$ par2 r file.par2

or :

$ par2repair file.par2

Or with Quickpar that works fine with Wine.

How do par2/repair by double-clicking from my file manager without opening a console ? Is there a par2 GUI ?

Those using KDE/Konqueror won’t have any problem associating par2 files with par2repair and letting the console open after the operation, it’s very straight forward.
With Gnome opening a gnome-terminal from Nautilus is tricky since it the window closes too quickly you can’t see what happened, so let’s use xterm instead :

In Nautilus, associate par2 extensions with custom command-line :

xterm -hold -e par2repair

About the Par2 GUIs there are several :

• Ben’s Par2GUI KDE script, which judging by the comments is very handy.
• Gpar2
• PyPar2
