Use C# to organise photos into date folders

I like to keep photos of my children in folders which are named based on the date the photos inside were taken. For example, all photos taken on Christmas Day last year are in a folder called 2010-12-25.

I finally got round to writing a quick C# console application to organise photos into folders automatically. The date the picture was taken is easy to get using the BitmapMetadata class.

Here’s the code:

using System;
using System.IO;
using System.Windows.Media.Imaging;

namespace OrganisePhotosIntoDateFolders
{
class Program
{
static void Main(string[] args)
{
string folderPath = "C:\\PhotosToOrganise";
if (args.Length > 0) folderPath = args[0];
foreach (string photoPath in Directory.EnumerateFiles(folderPath, "*.jpg"))
{
string subFolderName = "Unknown";
string photoFileName = new FileInfo(photoPath).Name;
DateTime dateTaken = DateTime.MinValue;
using (FileStream fs = new FileStream(photoPath, FileMode.Open, FileAccess.Read, FileShare.Read))
{
BitmapMetadata md = (BitmapMetadata)BitmapFrame.Create(fs).Metadata;
DateTime.TryParse(md.DateTaken, out dateTaken);
}
if (dateTaken > DateTime.MinValue) subFolderName = dateTaken.ToString("yyyy-MM-dd");
string subFolderPath = String.Format("{0}\\{1}", folderPath, subFolderName);
if (!Directory.Exists(subFolderPath)) Directory.CreateDirectory(subFolderPath);
File.Move(photoPath, String.Format("{0}\\{1}", subFolderPath, photoFileName));
}
}
}
}
