The .KZ extension is a file format commonly used for compressing data. This type of file is used by the KuaiZip software, a commercial Windows-based compression program that offers users the ability to compress multiple files quickly and securely. KZ files are useful in reducing the overall size of stored files in order to conserve disk space, as well as for speeding up file transfer times on a slow network.
Technical Details
The KZ file format can compress data up to 95 percent of its original size, with any remaining 5 percent intended for potential future additions or alterations. It is built upon standard compression algorithms such as LZMA, PPMd, and BCJ2c, with some proprietary technologies used for improving existing compression algorithms. In addition, the KuaiZip software provides AES 256-bit encryption, allowing users to securely encrypt a compressed KZ archive without sacrificing speed or file integrity. Other features include unicode support and multithreading capabilities.
Similar Formats
The KZ format is related to other compression formats such as .RAR, .TAR, .ZIP, .7z, as well as container formats such as .DMG, .ISO, and .EXE, which are used to store archives and multimedia files.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .KZ) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .KZ extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .KZ file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .KZ extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .KZ extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .KZ file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .KZ file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .KZ file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .KZ file) will be extended to the maximum.
It is also good to check
- if the .KZ file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
