What is WinCoreUtils?
WinCoreUtils is a growing collection of small, focused, Windows-native command-line tools inspired by the classic GNU / Unix core utilities.
These tools are not ports, not wrappers, and not dependent on WSL. Although some have been named to avoid conflict with WSL tools.
ddd— Direct Disk Duplicatordf— Disk Usagelss— Directory Listinguptime— System Uptimelsusb— USB Deviceslspci— PCI Devicesv4lwin— Video Capture Devices
They are written directly against the Windows API using Delphi, producing fast, standalone executables that feel at home on Windows while retaining the clarity and utility of their Unix counterparts.
This project exists to fill the practical gaps where WSL, PowerShell, and existing Windows tooling fall short — especially when you just want a simple command that works.
Design Goals
- Small, single-purpose executables
- Native Windows behavior
- No background services
- No frameworks
- No dependencies
- Predictable output
- Easy to modify and extend
Each utility is intentionally standalone. If you only need one tool, you can take just that one.
Included Utilities
ddd — (Direct Disk Duplicator)
A Windows-native, dd-inspired command-line tool for writing raw images directly to physical disks.
C:\> ddd
Usage: dd if=<src> of=<dst> [bs=size] [count=n] [skip=n] [seek=n] [status=mode] [conv=notrunc] [list=1]
if=PATH Input file, \\.\PhysicalDriveN, "-" for stdin, or "zero" for null stream
of=PATH Output file, \\.\PhysicalDriveN, or "-" for stdout
bs=SIZE Block size (supports K, M, G). Must be multiple of 512 for physical drives.
count=N Number of blocks to copy
skip=N Skip N blocks in input
seek=N Seek N blocks in output
status=progress Show visual progress bar and speed (requires full size known)
status=eta Show Estimated Time of Arrival (ETA) after 100MB warmup
conv=notrunc Do not truncate output file
list=1 List available physical drivesTo list disks:
C:\Downloads> ddd list=1
Available Physical Drives:
--------------------------------------------------
\\.\PhysicalDrive0 Size: 931.51 GB
\\.\PhysicalDrive1 Size: 31.22 GB
--------------------------------------------------To write an image (with progress):

df — Disk Usage

Each tool builds into a single executable.
You can:
- Build from source using Delphi
- Drop the EXEs into a directory on your PATH
No installers. No registry entries.
Contributing
WinCoreUtils is intentionally open-ended.
You are encouraged to:
- Fork it

Final Thoughts
WinCoreUtils is about rediscovering the joy of small, dependable tools.
If you’ve ever typed a command out of habit and wished Windows had it — this project is for you.
Happy coding.
