You can group files in Explorer to make them easier to browse. This is especially useful for pictures. Let’s say you want to find a picture you took last week, but you took an awful lot of pictures. Hover your cursor over the Date taken heading, and then click the down-arrow. Then, click Group. You can also right-click the folder, click Group By, and then click Date modified.

Windows Vista groups your files by date. Now, you can also manage them using that grouping. Click the down-arrow to collapse a group, and click it again to expand it. Click the line itself to select the entire group so you can easily delete or move the files.
