About .TGZ files
What a .TGZ file is, and what's inside it.
A TGZ file is a gzip-compressed TAR archive, the same thing as .tar.gz, just spelled for old 8.3 filenames. On Windows use free 7-Zip or PeaZip, or run tar -xzf file.tgz in a terminal (Windows 10/11 include tar). On macOS, double-click and Archive Utility handles it. On Linux, run tar -xzf file.tgz. The format has no built-in encryption, so scan contents before running anything from an untrusted source.

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