A tar file contains files in a directory structure like you might write them on magnetic tape. To install Arch, you need to prepare the sd card, not like John Cage prepared his pianos, rather in the manner of the instructions likely provided elsewhere on their website, e.g. for the Beagle Bone Black, https://archlinuxarm.org/platforms/armv ... bone-black
. It's like the weed out classes for computer science, it's not that everyone can't pass them, it's that only those sufficiently motivated will.
Of course what's the point in making an os harder to install than it would be if you just gave people an image file? Well, people can say, "I use Arch." And others will go "Oooooh, yer cool, man." Of course they might shoot back, "Well, I use Slackware, it's just as hard to install as Arch and more of its users have a condescending attitude, so it's even better, so there." And then the Whose Distribution Is Harder To Install So It's Better wars begin.
Edit add: I forgot to actually try to help in any specific way, so I'll point out that 7zip (also written 7-zip) has a windows version that does tar files.
