With the continuous development of technology, people's lives are inseparable from computers and the Internet. In our daily use of computers, we sometimes encounter unusual file types. For example, many people may encounter caj files when opening files, but they do not know how to open them for free.
So, what is a caj file? The caj file is a file format unique to CNKI (China National Knowledge and Science Library). It is mainly used to store various book materials such as academic papers, journal articles, newspapers and magazines. The caj file can retain the complete format of the original text, including text, pictures, tables, formulas, directories and other contents. Therefore, caj files are of great significance in the field of academic research.
However, due to the particularity of the caj file format, many users will encounter some difficulties when opening this file. In fact, it is not difficult to open caj files for free. Several common methods will be introduced below.
First of all, CNKI officially provides a free caj file reader, which can help users open caj files. Users can go to the official website of CNKI to download and install the cajviewer software. After the installation is complete, users only need to drag the caj file into the software and click to open to read the file content.
Secondly, CNKI also provides a corresponding caj file reader on mobile devices. Users only need to search for "CNKI Reader" in the app store, download and install the app. Through this application, users can conveniently read caj files on their mobile phones or tablets.
In addition, if users do not want to install additional software, they can also try to convert caj files to other common formats online. Some online file conversion websites, such as Zamzar and Online Convert, provide caj file conversion services. Users only need to upload the caj file to be converted, select the format to be converted, and download the converted file after the conversion is completed.
In addition to the above methods, there are some third-party software that can also help users open caj files. One of the more commonly used software is WinRAR. Users only need to decompress the caj file to see its contents. However, it should be noted that the decompressed content of the caj file may not be fully displayed because the text and image information in the caj file may be encrypted or compressed.
To sum up, opening caj files is not a problem. Users can choose the official cajviewer software of CNKI, or try the CNKI reader application on mobile devices. If you don't want to install software, you can also find some online file conversion websites for conversion. Finally, third-party software such as WinRAR can also help users view the contents of caj files. It is hoped that the above methods can help users in need to better carry out academic research.
