What is a PWL file?
A .PWL file is a legacy Windows Password List file. Early versions of Microsoft operating systems, such as Windows 95, Windows 98, and Windows ME, used this format. The system created a separate .PWL file for each user account. This file stored network passwords, dial-up connection details, and login data for applications like Microsoft Money.
How to open PWL files?
Modern operating systems do not use or open .PWL files natively. Historically, users accessed this data automatically when they logged into Windows. Security researchers and system administrators often used specific command-line tools or legacy utilities, such as Cain & Abel), to extract text and recover passwords from these files.
Best practices and troubleshooting
Because .PWL files contain sensitive legacy data, you should handle them carefully. These files use basic encryption, but this encryption is weak by modern security standards. If you find a .PWL file on an old hard drive, do not try to open it with a standard text editor like Notepad. The content will appear as unreadable characters.
