All about KZ Files
The KZ file type is primarily associated with KuaiZip.
What is a KZ file?
KZ files mostly belong to KuaiZip by Dream Chaser. The KZ file is a compressed archive file created by the KuaiZip file compression/decompression utility. This is proprietary software developed by Dream Chaser, a Chinese company.
- Compression: The KZ file format reportedly offers much higher compression ratios than alternative formats. It provides 5-10 percent higher compression than 7Z and upto 30 percent higher compression than RAR.
- Features: The file format allows multi-volume and multi-mode compression, supporting the decompression of a large number of similar formats like ZIP, RAR and 7Z. The KZ format offers lossless compression.
- Compatibility: Since this is proprietary software, this format may only be decompressed using KuaiZip which is available on Windows and MacOS platforms. The utility itself has only been designed for Chinese users, and is unsuitable for non-Chinese speakers. This format is currently regarded as obsolete.
The KZ is also used by other programs such as VDJ as a KaraokeZip file that stores lyrics and MIDI data for karaoke music.
