Hello mrityunjaynath,

No, stick with the File::Copy::Recursive module. File::NCopy is deprecated, according to its own documentation:

File::NCopy - Deprecated module. Use File::Copy::Recursive instead.

To learn how to install modules, see the Monastery’s Installing Modules tutorials. If you already have App::cpanminus installed, the process is as simple as entering:

>cpanm File::Copy::Recursive
[download]

from the command line.

Another point: Where does $newpath come from? You need to declare and initialise it before it’s used:

...
my $newpath = ...;  # Provide an initial value here
my $source_dirrtl = $newpath . "/rtl";
...
[download]

Hope that helps,
