Download Directories and sub-directories & files in 1 go

Question

I have a JList which lists all the files and folders on my FTP Server, which I can navigate through. At the moment I can download a single file by selecting it. However, I wish to be able to select a folder and download the full contents of it, which may contain multiple subdirectories and files.

I know you can detect whether an item is a file or folder using dirDetails(), but I'm looking for a shortcut that will allow me to download all my files and folders from a directory in one go?

Answer 1

This is supported in edtFTPj/PRO (a commercial product), not in edtFTPj.

For the API, see

Answer 2

I have attempted to create my own mass download subroutine however, upon executing this subroutine I have found that I can only download 18 items in one go (there are 42 files in the folder) before the ftp connection disconnects itself. Is there a limit to how many items you can pass through get(localPath, remotePath) in edtFTPj?

A simplified version of my code is shown below:

for(int i=0;i<files[i].length;i++)
{
  ftp.get(local+"\\"+files[i].getName(),files[i].getName());
}

If you search the forums you'll find numerous posts on this problem. Essentially, the client machine runs out of sockets. You need to build in waits during the download process - see our API for an example.

Thanks for the quick reply.

Ok, I've added a sleep command

Thread.sleep(x)

and it appears to work, but obviously runs very slow. My program is an Applet so reducing the TIME_WAIT on the client machine is not not an option. Is there anyway of adjusting the time within the code?

Answer 5

nvm, just read the api for edtjpro. You handle clearing sockets in there, but if anyone knows away of doing this, it would be much appreciated.
