What is a .CAA file?
A .CAA file is a type of file known as a CleanApp Archive. What makes this file special is that it contains a link, specifically an HTTP link, that directs you to a Chinese academic article or book. These articles or books are stored online on a website called www.cnk.net. The way a .CAA file works is quite similar to how .URL or .WEBLOC files function, which you might be more familiar with. These types of files act like shortcuts, meaning they quickly take you to a specific webpage or online resource. In the case of a .CAA file, the shortcut leads to an academic book or article that you can then download and view using a specific program.
The program that is used to open a .CAA file is called CNKI CAJViewer. However, it's important to note that this program has been discontinued, which might affect how you access the content in a .CAA file. Despite this, the .CAA file format is particularly popular among Chinese students and researchers. One of the reasons for its popularity is the file's small size. Since a .CAA file only contains a short string of text (the link), it is very lightweight and easy to share. This is especially useful for sharing links to large academic journal downloads without having to deal with large file sizes.
When you double-click on a .CAA file, if you have the CNKI CAJViewer installed, it will automatically open this file. The program then starts the process of downloading the journal or academic content that the .CAA file links to. During the download, a control window appears. This window provides you with useful information about the download process, such as the name of the journal being downloaded, the total file size of the download, and the rate at which the download is happening.
It's worth mentioning that CNKI stands for China National Knowledge Infrastructure, which is a significant resource for academic and research materials in China. Despite the discontinuation of the CNKI CAJViewer, the .CAA file format remains a testament to the infrastructure's commitment to making academic resources accessible and easily shareable among students and researchers.
