Hi Sreenivasarao,
You can also use SFTP connector in Mendix Marketplace to access remote server files
Check the below link for the SFTP module

Hope it help!
If the remote server supports some sort of FTP, you could use the marketplace module: sFTPs by Mendix.
Which allows you to connect, list files, move files to the FTP server and get files from the FTP server.
