File Organizer Scripts

Two JScript tools to automatically organize files into date-based folders (YYYY-MM-DD format).

Scripts Overview

Script	Files Processed	Date Source	Speed
groupFilesByDate.js	All files (except .js)	Last Modified Date	Fast: 7ms/file
groupJpgByExif.js	JPG/JPEG only	EXIF Shooting Date	Slower: 70ms/file

Features

• Creates folders named by date (e.g., 2025-11-09)
• Automatically moves files into corresponding date folders
• Reports number of folders created and files moved
• Prevents duplicate file overwrites

Requirements

• Operating System: Windows (tested on Windows 10 & 11)
• Runtime: Windows Script Host (WScript)
• No installation required - uses built-in Windows components 😎

Usage

Both scripts follow the same usage pattern:

1. Place the script in the target folder

2. Run the script

   • Double-click the .js file

3. Confirm the operation

   • A dialog will show the number of files to be processed

4. Wait for processing

   • Files will be moved into date-named folders progressively
   • groupJpgByExif.js will display a PowerShell window during processing

5. Check the results

   • A summary message shows folders created, files moved, and files skipped

Example

Before:

📁 My Photos
  🖼️ photo1.jpg (modified: 2025-01-11)
  🖼️ photo2.jpg (modified: 2025-01-11)
  🖼️ photo3.jpg (modified: 2025-01-14)
  📄 document.pdf (modified: 2025-02-20)
  📜 groupFilesByDate.js
  📜 groupJpgByExif.js

After (using groupFilesByDate.js):

📁 My Photos
  📁 2025-01-11
    🖼️ photo1.jpg
    🖼️ photo2.jpg
  📁 2025-01-14
    🖼️ photo3.jpg
  📁 2025-02-20
    📄 document.pdf
  📜 groupFilesByDate.js
  📜 groupJpgByExif.js

After (using groupJpgByExif.js):

📁 My Photos
  📁 2025-01-11
    🖼️ photo1.jpg
    🖼️ photo2.jpg
  📁 2025-01-14
    🖼️ photo3.jpg
  📄 document.pdf (not moved)
  📜 groupFilesByDate.js
  📜 groupJpgByExif.js

Notes

groupFilesByDate.js

• Processes all file types except .js files
• Uses DateLastModified property (not created date or EXIF)

groupJpgByExif.js

• Processes JPG/JPEG files only
• Uses EXIF DateTimeOriginal (shooting date from camera)
• Slower - requires PowerShell to extract EXIF data
• Photos without EXIF data are skipped (e.g., screenshoot, internet image)

Development Notes

Why JScript + PowerShell?

• Goal: Keep scripts small, portable, and easy to modify.
• Why not ExifTool? Requires external installation. PowerShell's System.Drawing is built into Windows.
• Why not pure PowerShell (.ps1)? Cannot be double-clicked to run. Requires command line knowledge.
• Solution: JScript wrapper provides GUI dialogs and can call PowerShell internally. Best balance of functionality and user experience.

Performance Comparison

Script	Averge ms per file
groupFilesByDate.js	7 ms
groupJpgByExif.js	70 ms
