UHARC CMD Guide: How to Compress Files to Extreme Sizes

UHARC CMD Guide: How to Compress Files to Extreme Sizes UHARC is a legendary high-ratio file archiver. It achieves significantly better compression than standard ZIP or RAR formats. While it is an older tool, it remains highly effective for multimedia and large datasets. Because it operates strictly via the Command Prompt (CMD), mastering its commands is essential.

This guide provides a practical walkthrough for installing and using UHARC via CMD. Setting Up UHARC

UHARC runs as a portable command-line utility. Follow these steps to prepare your system:

Download the uharc.exe executable from a trusted archive repository.

Create a dedicated folder on your system, for example: C:\uharc. Move the uharc.exe file into that folder. Open the Windows Command Prompt. Navigate to your folder by typing: cd C:\uharc Core Command Syntax

The basic structure of a UHARC command requires the executable, a specific command mode, the target archive name, and the files you want to compress. uharc.exe [command] [archive_name.uha] [file_or_directory] Use code with caution. Essential Command Modes a: Add files to an archive. e: Extract files to the current directory. x: Extract files with full folder paths. l: List the contents of an archive. Compressing Files to Extreme Sizes

To achieve maximum compression, you must use specific switches that adjust the compression mode and memory allocation. The Max Compression Command

Type the following command into CMD to compress a folder with extreme settings:

uharc a -mx -md64M -pr archive_name.uha C:\YourTargetFolder*. Use code with caution. Parameter Breakdown

-mx: Enables the multimedia and maximum compression mode. This tells UHARC to use its strongest algorithms.

-md64M: Allocates 64 megabytes of dictionary memory. A larger dictionary allows the tool to find more patterns across large files.

-pr: Includes all subdirectories and preserves the internal folder structure.

.: Instructs the tool to grab every file extension type inside the target directory. Extracting UHA Archives

Extracting files requires you to switch the primary command from creation to extraction. Extracting with Folder Structure

To unpack your files while keeping the original folder layout intact, use this command: uharc x archive_name.uha Use code with caution. Extracting to a Specific Location

If you want to extract the files directly into a completely different folder, use the output switch: uharc x -oC:\ExtractedFiles archive_name.uha Use code with caution. Performance Considerations

While UHARC offers impressive compression ratios, it comes with specific trade-offs:

Speed: Extreme compression (-mx) requires significant time to process. It is much slower than modern tools like 7-Zip.

Memory Limits: The maximum dictionary size is capped due to the software’s age. It cannot utilize modern multi-core processors effectively.

Compatibility: The .uha format is proprietary. Recipients must have UHARC installed to open your files.
