About .Z02 files
What a .Z02 file is, and what's inside it.
A .z02 file is the second segment of a ZIP archive that was split into several pieces (.z01, .z02, and a final .zip). You cannot open the .z02 directly: place all parts in one folder and open the last file (the one ending in .zip) with 7-Zip or WinRAR. If any part is missing, especially the final .zip, the archive cannot be extracted.

Do I have to unpack the whole .Z02 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 .Z02 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.
