# mozfile — Library of file utilities for use in Mozilla testing

License: copyleft · Maintenance: abandoned · Downloads: 486.6K/mo

## What it is and what it does

mozfile is a file utilities library built for Mozilla's testing infrastructure. It wraps common file and directory operations—such as temporary file creation, directory scanning, and file comparison—into a reusable API designed for test automation. The package depends only on six for Python 2/3 compatibility, making it lightweight to install.

The package is abandoned: its last release was over 1401 days ago, and there are no active maintenance signals. It was part of the mozbase project, a suite of testing tools used internally by Mozilla. If you are working with legacy Mozilla test code or maintaining an older test suite that already depends on mozfile, it will install cleanly, but you should not adopt it for new projects. No known security vulnerabilities are recorded.

Use it for:

- Managing temporary files and directories in Mozilla test automation scripts.
- Performing file comparisons or directory traversal in test fixtures.
- Maintaining legacy Mozilla test infrastructure that already depends on mozfile.
- Accessing file utilities from the mozbase testing toolkit in older codebases.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides file and directory utilities for Mozilla testing workflows, including operations like temporary file management, directory traversal, and file comparison.

No, unless you are maintaining legacy Mozilla test code. The package is abandoned with no recent updates and should not be adopted for new projects. If existing code already requires it, installation is low-friction, but consider migrating to actively maintained alternatives for new test infrastructure.

## Install

pip install mozfile
uv add mozfile
poetry add mozfile

## Installing mozfile

Before you install: Low install friction with a single lightweight dependency (six). However, the package is abandoned—last released 1401 days ago with no recent maintenance signals. Use only if you are maintaining legacy Mozilla test infrastructure.

License in practice: Licensed under MPL (Mozilla Public License 2.0), a copyleft license. You must disclose source modifications and license your derivative work under MPL 2.0 if you distribute it.

Quickstart:

pip install mozfile
import mozfile
# Use mozfile utilities for file operations in Mozilla testing

Verify before relying:

- What specific file operations the package provides (the fact sheet does not detail its API surface).
- Whether the package is actively used in current Mozilla testing infrastructure or is purely legacy.
- Compatibility with modern Python versions beyond 3.10 (classifiers list 3.6–3.10 but no newer versions).
