Alternatively called recursive, recurse is the procedure capable of being repeated. For example, when listing files in a Windows command prompt, you can use the dir /s command to recursively list all files in the current directory and any subdirectories. To better illustrate this concept, look at the picture of a hierarchical file system. Using the dir /s command on the C:\Windows directory also lists all files in the C:\Windows\system32, C:\Windows\Tasks, and C:\Windows\Web directories.
