  4. Folders will be protected from any organization operations

Category 2: Collision & Conflicts Handling

3️⃣ File Collision Handler - 4 Strategies ⚡

Location: "⚙️ Settings" tab → "Default Collision Strategy"

What It Does: When a file with the same name already exists at the destination, the app chooses an action:

  • Skip 🚫

    • Does NOT move the file
    • Leaves original in source folder
    • Best for: Conservative, keep both versions

  • Overwrite 🔄

    • Deletes the old file at destination
    • Moves the new file there
    • Best for: Updates, newer versions

  • Rename with Suffix 📝

    • Renames to: photo_duplicate_2026-02-15-143022.jpg
    • Moves BOTH versions (old stays, new gets renamed)
    • Best for: Keeping both, avoiding accidental loss

  • Move to Conflicts Folder 📂

    • Creates a _Conflicts folder
    • Moves conflicting file there
    • Keeps everything organized
    • Best for: Manual review later

How to Use:

  1. Go to "⚙️ Settings" tab
  2. Find "Default Collision Strategy"
  3. Select your preferred strategy from dropdown
  4. Settings save automatically

Category 5: History & Reporting

4️⃣ Advanced History Filtering 🔍

Location: "📜 History & Undo" tab → Filter controls at top

Available Filters:

  • 📅 Date Range: From and To date pickers

    • Filter by specific date range
    • Last 7 days, last month, custom range

  • 🏷️ Operation Type: Dropdown

    • All (show everything)
    • MOVE (file moves)
    • DELETE (file deletions)
    • UNDO (undone operations)

  • ✓ Status: Dropdown

    • All (success + failed)
    • Success (only successful operations)
    • Failed (only failed operations)

How to Use:

  1. Go to "📜 History & Undo" tab
  2. Set date range, operation type, status as needed
  3. Click "Apply Filter" or "Refresh" button
  4. Grid updates to show matching records

Use Cases:

  • "Show all deletions from last week" → Look for an accidentally deleted file
  • "Show all failed operations from yesterday" → Debug what went wrong
  • "Show all successful moves in January" → Audit your organization activity

5️⃣ Export History to CSV 📊

Location: "📜 History & Undo" tab → "Export to CSV" button

Features:

  • Export filtered history to Excel-readable CSV format
  • Includes columns:
    • Timestamp (date & time)

    • Source Path (where file came from)
    • Destination Path (where file went)
    • File Name
    • Success (Yes/No)
    • Error Message (if failed)

How to Use:

  1. Apply filters if desired (to export specific records)
  2. Click "Export to CSV" button
  3. Choose filename and location
  4. Open in Excel for analysis
  5. Create reports, pivot tables, audit trails

Examples:

  • Export all failures to investigate what went wrong

Category 6: Performance & Settings

6️⃣ Undo History Limit Configuration 📌

Location: "⚙️ Settings" tab → "Max Undo History Operations"

Features:

  • Set how many undo operations to keep in database
  • Default: 500 operations
  • Range: 50 to 10,000 operations
  • Prevents database from growing too large
  • Automatic cleanup of old records

How to Use:

  1. Go to "⚙️ Settings" tab
  2. Find "Max Undo History Operations"
  3. Set the number (e.g., 500, 1000, 2000)
  4. Click "Save Limit" button
  5. Older records beyond this limit are automatically deleted

Why It Matters:

  • Prevents database bloat: Keep only what you need
  • Storage efficiency: Don't keep years of history
  • Better performance: Smaller database = faster queries
  • Memory management: Especially useful on smaller SSDs
