The /f command allows you to specify the following items: 

• Path (/f c:\Images) 
• Wildcard (/f c\:Images*.jpg) 
• Single file (/f c:\ImagesSample.jpg) 

All three of these options can be a single or multiple or any combination. For example, (/f c:\Images,c:\Other\*.wma,c:\Data\sample.mp3) adds all the images in the Images directory (folder), all the wma files in the Other directory, and the sample.mp3 file.
