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
