Convert PEPPER to another file type

To convert your PEPPER file to another format, you need Euclid Quantum or other Plugin software.

Convert a file to PEPPER

To convert other file formats to the "CAD Extension Module" file type, you need software like Euclid Quantum or a similar tool.

About PEPPER files

The .pepper file extension is a rare and legacy format primarily functioning as a software plugin for Euclid, a computer-aided design (CAD) system originally developed by Matra Datavision (later acquired by Dassault Systèmes).

Unlike standard 3D drawings (like DWG or STL) that store geometry, a .pepper file typically contains compiled executable code (Internal Format: EXE) used to extend the core functionality of the Euclid interface. These files act as dynamic modules or libraries - similar to a DLL in Windows - that allow the CAD software to perform specialized modeling tasks. Because they contain binary instructions rather than visual data, they cannot be directly converted into image formats like JPG or PDF.

Common Friction Points:

Inaccessibility: Users often discover these files in archived engineering projects and mistakenly attempt to open them as drawings.
Obsolescence: The Euclid software family (including Euclid Quantum) has largely been superseded by CATIA, making these plugins functionally useless without the original 1990s environment.
Security Risk: As these are essentially renamed Windows executables, unknown .pepper files should be treated with caution.

Practical Workarounds:
For archiving or inspection, the most practical "conversion" is renaming the extension to DLL or EXE to inspect its properties or dependencies using developer tools. To retrieve actual 3D data, one must locate the accompanying project files (e.g., EUC) rather than the plugin files.

Convert.Guru analyzes your PEPPER file, detects the exact format, and lets you read the text inside.

Users also converted PKGLIST, VXP and RPK files.

FAQ

If you want to convert PEPPER file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use Euclid Quantum or similar software from the "Euclid CAD Plugin" 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 PEPPER, try Euclid Quantum or another comparable tool in the "Euclid CAD Plugin" category.

The PEPPER Converter Story

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 PEPPER converter.
