Wikipedia is one of the most often visited websites by all of us. Did you know that the entire Wikipedia database can be downloaded?
Yes. The Wikipedia database can be downloaded along with images and can be used for offline purposes. The best part is it can also be downloaded in various languages.
The entire Wikipedia site data and the pictures on it can be downloaded and have to be extracted using a free utility like 7-zip.
Regarding the latest dump, this is what Wikipedia quotes :
Latest complete dump of English Wikipedia
In the past the dump process has had difficulty scaling to cope with the size of the very largest wikis, and as a result the system failed for several years to produce valid, complete dumps of the English-language Wikipedia.
As of September 2011 the system now splits the dump process into many smaller files, and seems relatively reliable.
The latest complete dump of the English-language Wikipedia can always be found at http://dumps.wikimedia.org/enwiki/latest/
Here is the official Wikipedia page describing the download process and the links.
