> Can anyone pse explain what directory recursion means? Im not a recusion expert but I hope the following shed some light :)
If you were searching directories for a file or building a list of all files in a directory you would want to look first in the base folder and then each sub folder and their subfolders etc etc until you find the file or run out of folders to search. The easiest way to do this (that I know of) is to use a recursive procedure. A recursive procedure is a procedure that calls itself. Obviously this can cause problems (like stack overflows) if the procedure gets stuck in a loop. example function FindFile(FileName, Directory : String) : Boolean; begin //Is file in current dir //Call FindFile for each directory in he specified directory until all have been checked or the file is found end; Not a great example but I hope this illustrates simple recursion.
