Disk Space Analyzer

⚠️If you encounter an execution problem (blue Windows window), please refer to the FAQ.⚠️

1. Brief Description

Disk Space Analyzer is a powerful and modern utility designed to visualize, analyze, and clean your computer's storage space. Developed in Python with a sleek Dark Mode interface, it allows you to quickly identify large folders, track down duplicates (identical or similar), and manage your files with a high level of security thanks to an integrated internal recycle bin.

Whether you are using a standard screen or high definition (4K), the interface adapts dynamically to offer optimal readability.

2. Detailed Features

🔍 Analysis and Visualization

Ultra-Fast Scan: Recursive analysis of folders and entire drives.
Intuitive Navigation: Clearly displays the current path (e.g., [D:] Storage or Folder\Subfolder).
Three Main Views:
1. Detailed List: A hierarchical view with icons, size, file count, and usage percentage.
2. Chart: An interactive bar chart displaying the “Top 15” largest items + the “Rest”.
3. Duplicates: An advanced search tool sorted by categories.

👯 Advanced Duplicate Management

The software offers a configurable three-level duplicate search engine:

Identical: Files having exactly the same size and name.
Similar (Words): Groups files sharing the same first words (based on defined separators like "_", "-", " "). Example: "Vacation_01.jpg" and "Vacation_02.jpg".
Similar (Characters): Groups files starting with the same characters (for files without separators). Example: "FinalProjectv1" and "FinalProjectv2".

Note: The lists are smart and exclusive (a file detected in “Words” will not clutter the “Characters” list).

🛡️ Security and Deletion

Internal Recycle Bin (Buffer): An extra layer of security that moves files to a software-specific Trash folder before permanent deletion.
Windows Recycle Bin: Ability to send directly to the system recycle bin.
Visual Feedback: Deleted files do not disappear suddenly; they instantly become grayed out in all tabs to indicate their status, allowing for easy restoration before refreshing.
Protection: Options allow you to totally disable deletion or require systematic confirmation.

💾 Archiving and Export

Automatic Backup: Each analysis can be archived (JSON format) to be consulted later without rescanning the drive.
CSV Export: Export data from the current view or the complete analysis to an Excel/CSV file.

🌍 Internationalization & Ergonomics

Bilingual: Instant switch between French and English without restarting (the interface remains at the same state).
Persistence: The software remembers your preferences (paths, sorting options, duplicate separators) and the active tab.
