Open Source Rust File Systems

fd is a program to find entries in your filesytem. It is a simple, fast and user-friendly alternative to find. While it does not aim to support all of find's powerful functionality, it provides sensible (opinionated) defaults for a majority of use cases. First, to get an overview of all available command line options, you can either run fd -h for a concise help message or fd --help for a more detailed version. fd is designed to find entries in your filesystem. The most basic search you can perform is to run fd with a single argument: the search pattern. Instead of just showing the search results, you often want to do something with them. fd provides two ways to execute external commands for each of your search results: the -x/--exec option runs an external command for each of the search results (in parallel), or the -X/--exec-batch option launches the external command once, with all search results as arguments.

ext4-win-driver is an open-source Windows filesystem utility that enables direct access to Linux ext4 partitions and disk images. Built with Rust and WinFsp, it mounts ext4 volumes as standard Windows drive letters accessible through File Explorer. An automatic background service detects compatible USB drives and SD cards when connected. Users can also mount disk image files through a File Explorer context menu. The utility supports read-write operations, including creating, modifying, renaming, and deleting files and directories. Command-line tools provide filesystem inspection, directory browsing, partition information, and integrity auditing without mounting. Its installer includes WinFsp dependencies, supports x64 and ARM64 systems, and offers configurable read-only mounting for safer filesystem inspection.

dysk is a Rust command-line utility for inspecting mounted filesystems on Linux and macOS. It is designed as a more flexible alternative to traditional tools such as df. The default view presents filesystem information in a readable table that can be customized with selected columns. Users can filter and sort results to focus on relevant disks or mount points. Structured output is available in JSON and CSV for scripts and automated workflows. Its filesystem-discovery logic is provided by the reusable lfs-core Rust crate. The project was previously called lfs and includes dedicated documentation for installation and advanced usage.

Cover your tracks during Linux Exploitation / Penetration Testing by leaving zero traces on system logs and filesystem timestamps. moonwalk is a 400 KB single-binary executable that can clear your traces while penetration testing a Unix machine. It saves the state of system logs pre-exploitation and reverts that state including the filesystem timestamps post-exploitation leaving zero traces of a ghost in the shell.
