About ALZ
ALZ is the archive ESTsoft's ALZip made before EGG, and Korean downloads, school files and blog posts from the 2000s still come as .alz. A big one was split into volumes, the .alz first and then .a00, .a01 and on, each small enough for an email or a forum post.
Each file is stored or packed with Deflate or ALZip's own Bzip2, and can be locked with ZIP's old password cipher. Its names are in Korea's code page, which apps that don't expect it show as gibberish.
Filepeek reads ALZ with a reader of its own after unalz, its Korean names read right, lists its files like a folder and opens the one you pick. A locked archive asks for its password, and Save as ZIP turns it into a ZIP that any computer opens.

Questions
Why are the names in my ALZ garbled?
ALZip writes names in Korea's code page without saying so, and apps that read them another way turn them into gibberish. Filepeek reads them as ALZip wrote them.
How do I open an ALZ split into .a00 and .a01 files?
Drop the .alz together with all its .a00, .a01 and later parts. They open as one archive.
What's the difference between ALZ and EGG?
Both are ALZip's. ALZ came first, and EGG followed in 2009 with LZMA, AES passwords and solid archives. Filepeek opens both.
Can I open a password protected ALZ?
Yes. Filepeek asks for the password when you open a locked file, and it stays on your device.
Can I turn it into a ZIP?
Yes. Choose Export, then Save as ZIP. Phones and computers open the ZIP without an app.
