使用`FTPClient`从FTP服务器下载文件的一部分

Question

Is it possible to download only a part of a file from my FTP server using FTPClient ? This part should by specified by two long values m and n meaning "starting from byte m untill byte n .

Is such a thing actually possible using the FTP protocol?

Answer 1

Using the ftp4j library you can do the following:

client.download("remoteFile.ext", new java.io.File("localFile.ext"), 1056);

The documentation describes this method as the following:

This one resumes the download operation starting from the 1056th byte of the file. The first byte transferred will be the 1057th.
