DnZip

DnZip is a .NET command-line tool for creating ZIP archives from one or more files and directories, with optional recursive directory inclusion and password-based encryption.

It is intended as a simple alternative to the default Windows ZIP workflow, especially when you need encrypted archives from the command line.

Package: DnZip on NuGet

DnZip is distributed as a .NET global/local tool package.

Features

• Create a ZIP archive from one or more files and directories
• Include subdirectories recursively
• Encrypt the archive with a password prompt
• Omit directory entries like zip -D
• Use Shift_JIS entry encoding for better compatibility with common Windows archive tools

Installation

You can install DnZip as a .NET tool:

dotnet tool install --global DnZip

You can also install it locally for a specific repository:

dotnet new tool-manifest
dotnet tool install DnZip

If you want to update an existing installation:

dotnet tool update --global DnZip

Usage

Syntax

dnzip [options] <archiveFilePath> <sourcePath> [sourcePath...]

Arguments

Argument	Description
archiveFilePath	Output path of the ZIP archive to create
sourcePath	One or more files or directories to archive

Options

Option	Description
-r, --recurse	Include subdirectories recursively
-e, --encrypt	Prompt for a password and create an encrypted ZIP archive
-D, --no-dir-entries	Do not create directory entries

Examples

Create a ZIP file from a directory:

dnzip output.zip ./data

Create a ZIP file including subdirectories:

dnzip output.zip ./data --recurse

Create an encrypted ZIP file:

dnzip output.zip ./data --encrypt

Create an encrypted ZIP file including subdirectories:

dnzip output.zip ./data --recurse --encrypt

Create a ZIP file from multiple inputs:

dnzip output.zip ./docs ./src/appsettings.json ./assets --recurse

Create a ZIP file without directory entries, like zip -D:

dnzip output.zip ./data --recurse --no-dir-entries

Behavior

• Returns exit code 0 on success
• Returns exit code 1 on failure
• Prints an error message if any source path does not exist
• Prompts twice for password confirmation when --encrypt is used
