To extract packages on archlinux, by default you can use command line like tar. But there's another easy way using file manager. But you must install required packages first.
For extracting zip files you need install zip & unzip
For extracting rar files you need install unrar
Software like winrar/winzip, you can try file roller, or xarchiver from AUR.
Install these packages first:
#pacman -S file-roller p7zip zip unzip unrar
Done. Then you can extract/unzip or compress into archive on file manager.
For GUI like winrar/winzip there are 2 apps installed fileroller and 7zip, both of them look OK, but File-Roller is better GUI and simple.
Another best archiver is xarchiver, but this package is not available anymore on official repositories, but available on AUR. Here's the link to install from AUR.
Download the tarball file, then extract it using tar -xvzf xarchiver.tar.gz
Then makepkg -s, after package created install it using sudo pacman -U *.pkg.tar.xz
Here's the GUI of xarchiver:
Ok, that's it, about three software above, i prefered file-roller, then xarchiver, and the last 7zip FM.
