4 Steps to Open an Unknown .ZLP File

A .ZLP file can come from different programs and isn't universally openable.

  1. Identify the Source: Often, these are email attachments quarantined by Zone Labs' ZoneAlarm Mailsafe, which renames potentially dangerous .REG files to .ZLP to prevent accidental execution.
  2. Check the Header: Inspect the first bytes in a text editor or hex viewer:
    • REGEDIT4 or Windows Registry Editor indicates a Windows Registry script.
    • "PK" implies a standard ZIP archive.
    • Readable XML/JSON suggests a configuration file.
  3. Use the Original Software: The original program is usually required. You may need Windows Registry Editor (after renaming to .REG), ZoneAlarm, or ask the sender if uncertain.
  4. Use this Webpage: Drag and drop the file into our viewer to detect the format, extract readable text/metadata, and preview when possible.
