At the top of the "Restore Files" dialog is a section where you specify the name of the file you want to restore:
here are two ways of finding a file
1) By location
2) By name
Finding a file by location
Most times you will know where the data file is that you want restored.
Finding a file by name
Sometimes you may want to find a file that was worked on in more than one directory, or you now the name of a file, but not the directory in which it was located. The "Search" button will help you find the file.
