Comment 2 for bug 134839

This is a feature not a bug!

Anyway technically it is possible to have a progress bar
but only for extracting and adding files from and to the archive. The problem is that
I'm alone in coding Xarchiver and unfortunately the archive navigation code
has introduced some misbehaviours that take time to be corrected.

Do someone want to take care of coding such real progress bar? Xarchiver knows
how many files are to be extracted/addded. At each line of output produced by
the command line archiver exe, the progress bar is to be incremented. The difficulty
is that arj,rar,7zip have a different way of outputting the lines.
