WHDArchiveExtractor is a dedicated tool for Amiga users working with WHDLoad

archives. It addresses the common issue of archives becoming corrupted when

extracted on non-Amiga platforms, ensuring a fully Amiga-compliant extraction

process. Designed with WHDLoad Download Tool users in mind, this utility

automates locating and extracting LHA and LZX archives across subdirectories,

faithfully recreating the original folder structure the archives were found in.

With the ability to automatically extract thousands of archives from a single

command, WHDArchiveExtractor streamlines the management of large archive

collections, although the total extraction time will depend on the speed of the

Amiga system. By extracting only new or updated files, the tool avoids

unnecessary duplication, optimizing disk space usage. With its Amiga-specific

approach, WHDArchiveExtractor uses Amiga tools to extract archives so they

retain their Amiga formatting, eliminating the risk of corruption that often

arises from extractions on non-native environments. This tool was created to

simplify managing my own WHDLoad folders, and i've release it publicly so

other may hopefully find some use from it.

Feedback, suggestions, and insights into your methods for transferring archives

from computers to the Amiga are welcome at Author email address above or via

the project's GitHub page.

KEY FEATURES

Scanning input folders and subfolders for LHA and LZX archives
Extracting the archives using the LHA or LZX programs to an output folder
Preserving the subfolder structure from the input folder during extraction
Extracting only new or updated files to avoid unnecessary duplication

PREREQUISITES

To use this program, ensure the LHA software is installed in the

C: directory. You can download it from aminet.net/package/util/arc/lha.

A very small number of archives require LZX to extract them. This can be

got from aminet.net/package/util/arc/lzx121r1

USAGE

$ WHDArchiveExtractor <source_directory> <output_directory>

For example:

$ WHDArchiveExtractor PC0:WHDLoad/Beta DH0:WHDLoad/Beta

This will scan the PC0:WHDLoad/Beta directory and extract all LHA archives

found to the DH0:WHDLoad/Beta directory, preserving the folder structure.

CHANGELOG:

[1.0.0] - 2023-04-28

- First release

[1.1.0] - 2024-03-12

- Added support for LZX archives.

- Improved error handling

- If the target folder already exists, it will now be scanned for protected

files and the protection bits will be removed. This is to allow the

extraction to replace the files if needed.

[1.1.1] - 2024-03-15

- Fixed some typos and text alignment issues
