Extract text from WinZip registration files (WZMUL)
To convert WZMUL registration files to another format, you need WinZip or other Settings software.
To convert other file formats to the "License Registration File" file type, you need software like WinZip or a similar tool.
A .wzmul file is a proprietary WinZip Registration File used to activate multi-user licenses. It contains encoded or encrypted authentication data that validates a bulk software purchase across an enterprise network. This file is exclusively designed to be processed by WinZip, a file archiver utility developed by Corel.
Users often attempt to convert or open this file to recover lost license keys or read the registration details. However, the .wzmul format has severe disadvantages for casual users: it is a closed, proprietary format that requires a paid software installation to function properly. It cannot be opened natively by web browsers, and opening it in standard text editors usually reveals garbled, encrypted strings.
Because it is a pure authentication token, converting a .wzmul file to typical formats like PDF or DOCX is generally impossible. If the data is unencrypted, extracting the raw text to TXT is the only logical target, though formatting will be lost.
This file format is exceptionally difficult to open or convert because it is built entirely for license verification. Often, only the original WinZip software can properly read or export the data. Standard online converters fail to process it because it is not a standard media or document format.
Convert.Guru analyzes your WZMUL file, detects the exact format, and lets you read the text inside.
If you want to convert WZMUL file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use WinZip or similar software from the "Software License Authentication" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to WZMUL, try WinZip or another comparable tool in the "Software License Authentication" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our WZMUL converter.
