WikiTaxi compresses all of Wikipedia into a database that's searchable, fully usable, and small enough to fit on an 8GB USB drive. WikiTaxi grabs the Wikipedia database dump every few weeks, keeping your offline entries up-to-date with the latest changes. There's also an option in the program to update it yourself, if you happen to find yourself near an Internet connection.
As a single-file app, WikiTaxi is easy to manage--hence the portability. To install it, you extract the file to any folder. When you open it, it opens to a randomly-selected page, and you can browse from there. WikiTaxi does leave Wikipedia's images behind to keep the file size down, so if you need graphics this might not be for you. Also, given the nature of WikiTaxi, don't forget that external links are not supported for obvious reasons. Internal links should still work, though. As a growing number of people try to take advantage of the Internet's resources without getting all the online distractions, WikiTaxi is a smart way to bus around one of the best tools on the Web.
WikiTaxi enables you to read, search, and browse Wikipedia offline. No Internet connection is needed, all pages are stored in a WikiTaxi database. Because Wikipedia is constantly growing, WikiTaxi uses compression to make sure that the database stays reasonably small. The huge English Wikipedia easily fits on a 8 GB memory stick.
WikiTaxi is multilingual, which means that you can use it for Wikipedias from different languages. It also works well with the dictionary and quotation Wikis, if you like. You can also save multiple Wikis to disk and use all of them with WikiTaxi. WikiTaxi is up to date. It works with the original Wikipedia database dumps, which are updated regularly every few weeks or so. If you feel that your offline Wikipedia is getting to old, you can go online to download a more recent version or just copy it from a friend.
Version 1.03 includes more parser improvements, one of which also fixes an AV.
