When I did this a number of years ago, and it was only around 5-6GB, or about 20GB with all the images. I also added about 4GB for windows, android, iOS, Linux, and Mac OS apps to parse/view the data. All of that fits on a 32GB flashdrive that I used to keep on my keychain but currently is in my glove compartment I think.

It sparks some amazement in me still to wrap my head around the reality of so much information in a thing the size of my pinky. Or the size of my pinky nail if you use a micro SD card. And yeah, just took a weekend of downloading and setting it up, and flashdrives/microsd cards are easily found at department stores, or even gas stations sometimes.

Even disregarded any potential doomsday utility, the amusement/amazement it's brought me was well worth the modest time/money it took. I hope more people give it a try

Has kiwix gotten any better? I tried to use it years ago, but it crashed more than once and had all sorts of blocking UI interactions.
