I would recommend using a module for manipulating paths. File::Spec is a core module, meaning you normally don't have to install it, and Path::Class is basically a nicer interface for it that gives you objects with lots of nice features.

use File::Spec::Functions qw/abs2rel/;
my $path = "C:\\Dir1\\Dir2\\Dir3\\KeepMe";
my $base = "C:\\Dir1\\Dir2\\Dir3";
print abs2rel($path, $base), "\n";  # prints "KeepMe"
# - or -
use Path::Class qw/dir file/;
my $path = dir('C:\\','Dir1','Dir2','Dir3','KeepMe');
my $base = dir('C:\\','Dir1','Dir2','Dir3');
print $path->relative($base), "\n";  # prints "KeepMe"

This code assumes it is being run on a Windows system - if you are instead manipulating Windows pathnames on a Linux or Mac system, there are ways to do that with the above modues as well.

s/$find/$replace/eeg

BTW, why are you using /eeg here? It doesn't seem necessary. (Plus, I would also anchor the regex to the beginning of the string with ^, just in case.)
