Linux/Unix/Mac OS X

• 1). Open the terminal. The procedure for doing this will depend on your version of Linux or Unix. In Mac OS X, you can open a terminal by clicking "Spotlight" and typing "Terminal."
  
  
• 2). Type the following command:
  
  find . -type d -name "FOLDER_NAME"
  
  The first argument (.) tells find to begin in the current directory. The "-type d" tells find that it is looking only for directories, not files. Finally "-name" tells find to search for folders by name.
  
  Replace "FOLDER_NAME" with the name of the folder you would like to search for.
  
  
• 3). Wait for the search to be run. Depending on the number of files and folders on the disk, this may take anywhere from a second to a few minutes.
  
  

Windows XP/Vista/7

• 1). Open the command prompt by clicking "Start," "Run," and typing "cmd."
  
  
• 2). Type the following command:
  
  dir FOLDER_NAME /ad /s
  
  The "/ad" tells dir to list only directories (those with (a)ttribute "d"). The "/s" tells dir to include sub folders. Replace "FOLDER_NAME" with the name of the folder you would like to search for.
  
  
• 3). Wait for the search to be run. Depending on the size of the drive, this may take anywhere from a few seconds to a few minutes.
