About .MPKG files
What a .MPKG file is, and what's inside it.
An MPKG file is a macOS installer meta-package created by Apple. It bundles several .pkg installer files so they run as a single installation session. Double-click it on macOS and Apple Installer opens it automatically. Windows and Linux cannot run MPKG files. The format is legacy (Apple replaced it with flat .pkg around 2012), but current macOS still opens it.

Do I have to unpack the whole .MPKG file?
No. The viewer reads its table of contents first and only unpacks a file when you click it. That works even with multi-gigabyte archives, because we read just the bytes we need.
Can I open password-protected archives?
Yes, for ZIP (ZipCrypto and AES) and 7Z. You'll be asked for the password,. We can't recover forgotten passwords.
Is my .MPKG file uploaded anywhere?
No. The code that unpacks the file is downloaded once and then reused.
Why does a .docx or .apk open as an archive?
Because they are ZIP archives under the hood. Office documents, Android apps, Java programs and EPUB books all use ZIP as their container.
What about split archives (.001, .z01, .part1.rar)?
Multi-part archives need all their parts. Today you can open the first part to see the file list; joining parts is on our roadmap.
