It’s okay as it is
ALZ and EGG seem to be one of frequently used formats in S. Korea. Many of the compressed files I get from Korean clients tend to be in ALZ or EGG formats, and I must comment on the fact that how blatantly nobody else in the world, including HWP format, uses such compression mechanism.
Apart from unique formats, the app itself is far from a universal archive file opener. It only supports few other formats and yet unreliable during the process. The only reason why I decided to download this app is to extract ALZ and EGG files. I’m not certain whether ALZip is serving its purpose as a “compression program,” other than clearing its own mess.
