To create a virtual folder:
- Press the WinKey+F, this brings up a search window.
- In the Search field type the words that you want to search for.
- When you have your search just the way you like it press the 'Save Search' button.
- Give your saved search a name (such as: "Personal Receipts")
Now all you have to do is open up the saved search and you have yourself a virtual folder. The file in this folder gets updated dynamically whenever it is open, which means any files that match your search get displayed.
