About .LZH files
What a .LZH file is, and what's inside it.
An LZH file is a compressed archive created with LHA (formerly LHarc), a format that dominated software distribution in Japan and on the Amiga through the 1990s. On Windows, open it with 7-Zip or PeaZip; on macOS, use The Unarchiver or Keka; on Linux, use lhasa or p7zip. The format is legacy now. Extract the contents and repack as ZIP or 7z for modern use.

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