If you want to Read/write/edit remote files transparently use this module

File::Remote

but deep in the linked info, "Unix only"

What remote access methods are enabled or allowed? (SSH/SFTP/SCP, Telnet, FTP, CIFS, NFS, HTTP, etc.)

Using the OS windows. SFTP enabled.

Are you being charged by keystroke or what?

Come on!, give a good description of your environment and what you want to accomplish if you really want to get any useful help!

You will need to provide far more context than you did.

As a long shot, I use the following to locally process the contents of a file that is stored encrypted on a machine reachable through ssh:

...

my $remote_file = "Storage/bar20100722.gz.gpg";
open my $fh, "ssh corion\@storage cat $remote_file | gpg2 --decrypt - 
+| gunzip -cd |"
    or die "Couldn't open '$remote_file' ";
};

...
