+# File copying
+
+### Description
+
+I built this program so I can back up my files with only new files or files that have changed since 
+the last backup. This program recursively walks down every directory tree until it finds a file, then adds or replaces
+this file into the backup directory. 
+
+### Functionality
+- Directory walking
+- Selective file copying
+
+### Instructions
+It uses only the standard library so can be run as is.
