cScan Enhanced - Major UX and Safety Improvements

Overview

Your cScan script has been significantly enhanced with comprehensive safety features, improved user experience, and full cross-platform support. Here are the key improvements:

Cross-Platform Support

Platform Detection

• Automatic OS detection: Detects Windows, macOS, and Linux automatically
• Platform-specific adaptations: Adjusts paths, commands, and features based on OS
• Unified interface: Same user experience across all platforms

Platform-Specific Features

| Platform | Trash System | Temp Locations | System Protection | |———-|————–|—————-|——————-| | Windows | Recycle Bin (PowerShell) | %TEMP%, AppData\Local\Temp | C:\Windows, Program Files | | macOS | Trash (osascript) | /tmp, ~/Library/Caches | /System, /Library, /Applications | | Linux | gio trash / ~/.local/share/Trash | /tmp, ~/.cache | /bin, /usr, /lib, /etc |

Cross-Platform Benefits

• Write once, run everywhere: Single codebase for all platforms
• Consistent behavior: Same safety features and UI across OS
• Platform-aware safety: Respects OS-specific system directories
• Native integration: Uses native trash/recycle systems

Safety Improvements

1. Smart File Analysis

• File categorization: Automatically categorizes files (system, media, documents, cache, temp, etc.)
• Safety assessment: Evaluates deletion safety with levels: safe, user, unknown, critical
• Critical path protection: Prevents deletion of system files and running applications
• Process checking: Detects files in use by running processes

2. Safe Deletion System

• Recycle Bin integration: Files go to recycle bin instead of permanent deletion
• Backup creation: Optional backup before deletion
• Deletion logging: Comprehensive log of all deletions with timestamps
• Safety blocking: Automatically blocks deletion of critical/system files

3. Enhanced File Information

• MIME type detection: Identifies file types accurately
• File age analysis: Shows creation, modification, and access times
• Usage detection: Checks if files are currently in use
• Path analysis: Categorizes based on file location patterns

User Experience Improvements

1. Smart Cleanup Suggestions

Instead of just showing a list of large files, the script now provides intelligent suggestions:

SMART CLEANUP SUGGESTIONS
═══════════════════════════════════════════════════════════

1. Old temporary files (7+ days old)
   Files: 15 | Size: 2.3 GB | Safety: safe

2. Cache files (can be regenerated)
   Files: 8 | Size: 1.1 GB | Safety: safe

3. Large files in Downloads folder
   Files: 5 | Size: 4.2 GB | Safety: user

2. Enhanced File Display

Files are now shown with context:

   4.36 GB [SAFE] models - C:\Users\user\.ollama\models\blobs\sha256-...
   2.54 GB [USER] cache - C:\Users\user\AppData\Local\pip\cache\...
   1.61 GB [UNKN] unknown - C:\Users\user\AppData\Roaming\Cursor\...

Indicators: [SAFE] = safe, [USER] = user confirmation needed, [UNKN] = unknown, [CRIT] = critical

3. Multiple Cleanup Modes

• Smart suggestions: Review AI-generated cleanup recommendations
• Manual review: File-by-file review with detailed info
• Category view: Browse files by category (media, cache, temp, etc.)

4. Enhanced Information Display

When reviewing files, you can now see:

• File category and safety level
• Last modified date
• MIME type
• Detailed path information
• Size and age

Configuration Enhancements

New Settings Added:

[Settings]
# Use Windows Recycle Bin instead of permanent deletion
use_recycle_bin = true

# Show safety warnings for dangerous operations
show_safety_warnings = true

# Enable dry run mode (show what would be deleted without actually deleting)
dry_run_mode = false

# Create backup before deleting files
backup_before_delete = false

Smart Analysis Features

1. File Categories

• System: .dll, .sys, .exe, .msi
• Media: .mp4, .avi, .mkv, .mov, .wmv, .mp3, .wav
• Documents: .pdf, .doc, .docx, .txt, .xlsx, .ppt
• Images: .jpg, .jpeg, .png, .gif, .bmp
• Archives: .zip, .rar, .7z, .tar, .gz
• Temp: .tmp, .temp, .cache, .log
• Backups: .bak, .old, .backup
• Virtual: .vhd, .vhdx, .vmdk, .vdi
• Models: .bin, .gguf, .model, .safetensors

2. Smart Suggestions Logic

• Old temp files: Files older than 7 days in temp directories
• Cache files: Files in cache directories (can be regenerated)
• Old backups: Backup files older than 30 days
• Large downloads: Files >500MB in Downloads folder

Usage Examples

Smart Cleanup Mode

python cScan.py
# Choose option 1 (CLI)
# When prompted, choose "1. Review smart suggestions"
# Review each suggestion with safety indicators

Manual Review Mode

# For each file, you can:
# y = delete file
# n = skip file  
# i = show detailed info
# q = quit deletion
# a = delete all remaining

Category View

# Browse files by category:
# 1. Media - 12 files (8.2 GB)
# 2. Cache - 25 files (1.5 GB)
# 3. Temp - 8 files (500 MB)

Safety Guarantees

Files That Will NEVER Be Deleted:

• System files in Windows directories
• Files from currently running processes
• Critical system libraries (.dll, .sys, .ocx)
• Files in use by active applications
• Microsoft-specific application data

Default Safety Behavior:

• Files go to Recycle Bin (can be recovered)
• Critical files are automatically blocked
• Smart suggestions prioritize safe deletions
• All deletions are logged for review

Requirements

The enhanced version requires:

psutil>=5.9.0

Install with: pip install psutil

Key Benefits

1. Safer: Multiple safety layers prevent accidental deletion of important files
2. Smarter: AI-like suggestions help identify what’s actually worth deleting
3. Faster: Categorized view lets you quickly identify cleanup opportunities
4. Recoverable: Recycle bin integration means mistakes can be undone
5. Informative: Rich file information helps you make better decisions
6. Logged: Complete audit trail of all cleanup operations

Migration from Original Version

The enhanced version is fully backward compatible. Your existing configuration will work, but you’ll get additional safety features and smart suggestions automatically.

Logging

All deletions are logged to: %TEMP%\cScan_backups\deleted_files.json

Example log entry:

{
  "timestamp": "2024-01-15T14:30:45.123456",
  "filepath": "C:\\Users\\user\\temp\\old_file.tmp",
  "size": 1048576,
  "category": "temp",
  "safety": "safe"
}

This comprehensive enhancement makes cScan significantly safer and more user-friendly while maintaining all original functionality.
