Hi, I always appreciated the portable application approach (and your high quality portable software repository).
I recently developed PeaZip (now at it's 1.1 release), a file archiver and compressor (featuring also file split and two factor authentication encryption) that is basically a portable, autocontained application having all it needs (executables, configuration files etc) in the program's folder.
"PeaZip1.1_Win32.zip" doesn't need installation, you just need to extract and start using it; you can move it and run it from the path you prefer, i.e. form a removable media, a network path or even a CD/DVD rom, however a writeable path is recommended in order to allow updating of persistent randomness collector and configuration files.
I also tryed to keep the disk occupation low using strip and UPX on executables and the total space occupation is currently below 3MB (I know, it could be better!).
Current release downloadable packages are at:
The package "PeaZip1.1_Win32.zip" contains the portable application compiled for Windows (tested on 98, 2000, XP home and pro); if you are or will get interested in portable apps for Linux, the two Linux packages (for GTK1 and GTK2) follows the same philosophy and are standalone, protable applications as well (save for the fact that Linux versions requires libgdk_pixbuf library installed in the system).
I hope you may get interested in trying the software, please feel free to ask me anything about it.
I also hope you may find it interesting enough to be worthy of being listed as utility in your software repository, if not please consider that it is a young application and that I'm currently actively developing it, so you may check it in next months to see if you find something new that may be interesting.
