How to copy a file on the FTP server to a directory on the same server in Java?

Question

I\'m using Apache Commons FTP to upload a file. Before uploading I want to check if the file already exists on the server and make a backup from it to a backup directory on

Answer 1

To backup at same Server (move), can you use:

String source="/home/user/some";
String goal  ="/home/user/someOther";
FTPFile[] filesFTP = cliente.listFiles(source);

clientFTP.changeWorkingDirectory(goal);  // IMPORTANT change to final directory

for (FTPFile f : archivosFTP) 
   {
    if(f.isFile())
       {
        cliente.rename(source+"/"+f.getName(), f.getName());
       }
   }
