Hi,
I am writing a program to determine if a file exists. I can get the program to search a specified folder but i also need the program to search sub folders in the main folder sepecified. Is there any simple way of doing this?
Thanks for your time

well, if you want to search through the folders.. just create a function which calls himself when a new dir is found, and stop all the functions when the file is in the directory

.

Something like this:

(Toggle Plain Text)

public function CheckDir(the filename, the current directory)
  loop through the directory content
    if there is another directory found
       CheckDir filename, the directory to search for now
    else if a file has been found and it is called filename
       CheckDir = the current directory
    end if
  end loop
end function

The dir function will always return items in alphabetical order.
The second parameter dictates which type(s) of objects are enumerated (files/folders/drives or objects with certain attributes).
So your method might be

(Toggle Plain Text)

Routine ListDirectory(Path)

    List each directory and Call ListDirectory(directory's path)

    List each file and add its path to list of items

End Routine

Calling ListDirectory would then list all files in a particular directory, including subdirectories.

Simple!
