What is Kiwix?
Kiwix is an offline reader - meaning that it allows you to check text or video that is normally only available on the internet. We turn various online educational contents (such as Wikipedia, for example) into ZIM files, and these can be opened by Kiwix even if you are no connection whatsoever.
Where is the Wikipedia content?
My ZIM file is too big. What should I do?
In some languages, Wikipedia in particular can be particularly heavy (it's more than 5 millions articles, after all). Consider hosting your ZIM file onto a SD card, or download a version without images (nopic).
How often do you refresh your files?
Monthly in theory, every quarter in practice.
Can I update only the new content, or do I need to re-download the whole file?
No it is (unfortunately) not possible. You need to download a new ZIM file.
I have downloaded a ZIP file but I can't unzip it. The file seems corrupted.
I can't copy Kiwix on my USB flash drive because the index files (*.idx directory) are too big.
USB flash drives are often formatted using the FAT32 filesystem which can't store files bigger than 4GB. We recommend to use exFAT or NTFS which can deal with big files and are broadly supported.
Autorun does not work for USB keys?
It looks like the autorun functionality has been blocked for Windows 7 and higher.
