Save Sitecore Media Item to Disk file

Once we required to convert the Sitecore Media Item to a disk file (Save media item as a physical file on server). Sitecore does not provide any API to do this directly.

Below is the code to do it, thought to post it if can help others..
    string mediaItemPath = "/sitecore/media library/Images/myimage";
    string diskFolderPath = @"D:\Sitecore-Media\";

    MediaItem mediaItem = (MediaItem)Sitecore.Context.Database.GetItem(mediaItemPath);
    ConvertMediaItemToFile(mediaItem, diskFolderPath);


    public static void ConvertMediaItemToFile(MediaItem mediaItem, string folderName)
    {
        if (mediaItem.InnerItem["file path"].Length > 0)
            return;

        string fileName = folderName + mediaItem.Name + "." + mediaItem.Extension;

        var blobField = mediaItem.InnerItem.Fields["blob"];
        Stream stream = blobField.GetBlobStream();
        if (stream == null)
        {
            return;
        }

        string relativePath = Sitecore.IO.FileUtil.UnmapPath(fileName);
        try
        {
            SaveToFile(stream, fileName);
            stream.Flush();
            stream.Close();
        }
        catch (Exception ex)
        {
            Log.Error(string.Format("Cannot convert BLOB stream of '{0}' media item to '{1}' file", mediaItem.MediaPath, relativePath));
        }
    }

    private static void SaveToFile(Stream stream, string fileName)
    {
        byte[] buffer = new byte[8192];
        using (FileStream fs = File.Create(fileName))
        {
            int length;
            do
            {
                length = stream.Read(buffer, 0, buffer.Length);
                fs.Write(buffer, 0, length);
            }
            while (length > 0);

            fs.Flush();
            fs.Close();
        }
    }

  1. There is also a module on the marketplace that converts file based medio to blob storage and vice verso

    1. Hi Christophe, thank you for reading and commenting this post.

      You are right. This chunk of code will be useful if someone wants to achieve this with some custom way. Else this tool is really awesome. :)
