Your question isn't terribly clear, but if you need to move a file, I would use: 
use File::Copy qw( move ); 
move( $file_in_old_location, $new_location );

If you need to change the working directory, you'd just use the chdir built-in command. You can save the current directory if you need to like so: 

use Cwd;
my $pwd = cwd();
chdir( $somewhere_else );
# ... now you can do something over there 
chdir( $pwd );  # restores original location.

If that's not what you needed to know, try asking again.
