Well not quite but close. I’m holding a hard disk that has ALL of Wikipedia’s text in 10 different languages.
Yes you can download all of Wikipedia and yes it can easily fit in a hard drive. Isn’t that amazing? Text is incredibly dense compared to images and video. Around 22 GiB for English Wikipedia alone and 56 GiB for the 10 languages I downloaded.
I also have all of Wiktionary in the same hard drive. It’s around 16.4 GiB.
It’s only the raw text in json line files. No media and no markup. I think I downloaded a compressed dump then used wikiextractor to extract the text.
Does it include each article’s edit history, talk page, etc?
