File transfer from UNIX server to Windows server path

Question

Hello Experts, (Gud Even Gud Aft & Gud Mor)
Is there a way to transfer file from UNIX server(Oracle database), to Windows server? All I know if Windows path. I am able to read the file as it is on server, however it does not recognize Windows directory at all.
If you can share some documents around this to study, I will be grateful.
Regards,

NFS on the Unix server sharing the directory containing the file. FTP server on Unix allowing the file to be read and copied. OpenSSH on the Unix allowing the file to be read and copied via scp (secure copy).
But seeing as this is an Oracle database forum (not an operating system forum), and the subject matter is the database server languages SQL and PL/SQL, here is a PL/SQL solution.
Create a table using the BFILE data type for referencing the files on the Unix o/s. Provide a web enabled procedure for downloading the files via HTTP using a web browser. This procedure will look something as follows:
--// URL example: http://my-server.my-domain.com/MyDAD/MySchemaName.StreamFile?fileID=1234
create or replace procedure StreamFile( fileID number ) AUTHID DEFINER is
        mimeType        varchar2(48);
        fileName        varchar2(400);
        lobContent      BLOB;
begin
        --// read the LOB from a table (this example uses the
        --// Apex file uploads table - change it to your own files table)
        select
                f.filename,
                f.mime_type,
                f.blob_content
                        into
                fileName,
                mimeType,
                lobContent
        from    FLOWS_FILES.WWV_FLOW_FILE_OBJECTS$ f
        where   f.id = fileID;
        --// format a basic HTTP header that describes the file stream send
        OWA_UTIL.mime_header( mimeType, FALSE );        -- e.g. text/csv text/plain text/html image/gif
        HTP.p( 'Content-Disposition: attachment; filename='||fileName );
        HTP.p( 'Content-Length: ' || DBMS_LOB.GetLength(lobContent) );
        OWA_UTIL.http_header_close;
        --// now write the BLOB as a mime stream using the Web Procedural Gateway's
        --// doc load API
        WPG_DOCLOAD.download_file( lobContent );
exception when OTHERS then
        --// Decide what HTML to generate (if at all) if there is a failure
        --// (usually not a good idea to show database errors to the
        --// web browser client as that can provide technical details
        --// that could be useful for exploiting the database)
        HTP.prn( 'StreamFile() failed with '||SQLERRM(SQLCODE) );
end;
/ On Windows, IE can be used interactively to copy the file across. For automation (via PowerShell or console jobs), use a command like tool like wget* to download the file.
If you do not want to use SQL or PL/SQL as the file copy mechanism, then please close this thread (mark as answered) and take your question to an appropriate forum.
