FAQ
Answers to common questions about Encyclopedia 2000.
Getting started
What computers does it run on?
Windows 10 or 11, macOS 13 or later (Apple Silicon and Intel), and 64-bit Linux (Ubuntu, Debian, Linux Mint, and similar). More Linux packages, for Fedora, Arch, and other distributions, are on the way. There's no phone or tablet version yet.
Installer or portable version?
On Windows, the installer is best for most people: it adds the app to the Start menu and updates itself. The portable version runs without installing, even from a USB drive, and keeps its settings in a folder next to it.
How do updates work?
On Windows and Mac, updates download and install by themselves. On Linux, the app tells you when a new version is out, and you install the new .deb.
Is it suitable for children?
The articles are regular Wikipedia, written for a general audience, so some cover grown-up topics. The activities and games are fine for all ages.
Offline reading
How do I read without the internet?
Open Tools → Offline Library (on a Mac, Encyclopedia 2000 → Offline Library) and download a library. Then you can read, search, and explore Wikipedia with no connection. Videos, sounds, and a few live features still need the internet.
Which library should I choose?
Essentials has the best 220,000 articles with pictures, in about 7 GB, and is right for most people. Everything has all 7 million articles. Both also come without pictures, which makes them much smaller. Each size is shown before you download.
Where do the libraries come from?
From Kiwix, a nonprofit that packages Wikipedia for offline use. Encyclopedia 2000 downloads their files straight from Kiwix and its mirror servers, and checks for new editions.
Can I use a Wikipedia file I already downloaded from Kiwix?
Not yet; it's coming in the next update. For now, the app downloads its own copy.
Can I keep the library on a USB drive?
Yes. In the Offline Library window, use Change… to save it to any folder, including an external drive. If the drive is unplugged, the library opens again on its own when you plug it back in.
Other languages, or other Kiwix content like Wiktionary?
Not yet. Encyclopedia 2000 reads the English Wikipedia for now.
Privacy and safety
Does it collect any information about me?
No. There are no accounts, ads, analytics, or tracking, and your favorites and settings stay on your computer. Read the privacy policy.
Why does Windows warn me when I run it?
Windows SmartScreen warns about apps it hasn't seen many people download yet, which happens with each new version for its first days. Encyclopedia 2000 is signed by its publisher. If you see "Windows protected your PC", click More info → Run anyway. The warning goes away as more people download the new version.
