How can I download a Wikia for offline reading? Is there a specific service that I can use to download a Wikia? Once done, how can I read the downloaded file? I don't need images or other media files, but HTML formatting will be nice!
Each Wikia site should have an XML dump available on their
The XML dump is essentially one large file that includes the Wikia's text (as well as any markdown or tags used for page formatting), but not images. If you are on Windows you'll need an archive utility, such as 7-Zip or WinRAR, to extract the file.
I am less familiar with a specific reader that will assist you; you may simply want to install MediaWiki locally and import the XML dump. Failing that, I would recommend taking the second half of your question to Super User.
