4 Steps to Open an Unknown .ZLT File

Because .ZLT files can originate from different programs, they aren't universally openable.

  1. Identify the Source: If received via email, it may be a quarantined internet shortcut, suggesting ZoneAlarm Mailsafe. If from a corporate workflow, it might be proprietary data.
  2. Check the Header: Open the file in a text editor or hex viewer to inspect its first bytes:
    • [InternetShortcut] indicates a renamed .URL file.
    • "PK" suggests a renamed ZIP archive.
    • Readable XML/JSON implies structured data.
  3. Use the Original Software: The original program is usually required; try Zone Labs' ZoneAlarm, a web browser, or ask the sender if uncertain.
  4. Use this Webpage: Drag and drop your file into our viewer to detect the format, extract readable text/metadata, and preview when possible.
