- Write the name you want to give your new folder.
- Press ↵ Enter.

Step 4. Add subfolders inside the main folder
Double-click the name of the parent folder to open it. In the same way that you created the main folder, you can create subfolders to organize your files.

Step 5. Move the files to the new folders
You can open two Windows Explorer windows side by side, and then drag files from the original location to the new folder.

Advice
- It would be nice if you rename the files to add the creation date, so you can easily sort the files alphabetically and they will appear ordered by creation date. When renaming files to include the date as part of the name, use the format YYYY. MM. DD. For example, 2010.09.29. You can skip the century digits and just use 100929.
- To sort files by name in Windows Explorer, click the "Name" column heading.
- When you connect an external hard drive to your computer, you will be asked if you want to use the drive to create a backup via "Backup and Backup" on Windows or "Time Machine" on Mac.
