Hi ,, I have a tree of files I am trying to go inside each one and change one word from old to new somthing like : 
while files 
{
open (firstFile, " c:/file")or die;
if ( $_ eq " old " )
$_ = " new ";
}

[download]
so I got the logic but how do I open the directory containg these files and its subfiles and start reading each file at the time knowing that some files have subfiles which need to be changed as well ,, thanks
