What to Do When a .ZLN File Fails to Open

A .ZLN file can originate from different programs and isn't universally openable.

Identify the Source: These files often come from email attachments quarantined by Zone Labs' ZoneAlarm Mailsafe (representing a renamed .PCD file), or from legacy system backups.
Check the Header: Inspect the opening lines in a text editor or hex viewer. You might see:
- "PCD_IPI" confirming a Photo CD image.
- "PK" indicating a renamed ZIP archive.
Use the Original Software: The original program is usually required. Try renaming the extension to .PCD and opening it with IrfanView or Corel PaintShop Pro, or ask the sender if uncertain.
