FXComparer

FXComparer is a JavaFX desktop application that allows users to compare the contents of two archive files (such as ZIP, JAR, or other supported formats). The application provides a user-friendly interface to visualize differences between archives through intuitive file comparison.

Features

• Dual Archive Selection: Load two archive files either through file selection dialogs or by drag-and-drop functionality
• Visual Comparison: View differences in a clear, tabular format with color-coded status indicators
• Multiple Views: See file entries categorized as:
  • New (files present only in the second archive)
  • Removed (files present only in the first archive)
  • Modified (files present in both archives but with different content)
  • Same (files present in both archives with identical content)
• Detailed Information: View file size differences and comprehensive archive statistics
• User-Friendly Interface: Intuitive JavaFX UI with drag-and-drop support for easy file loading

• ZIP/JAR files
