------------------------------
Confirmed. Sorry, I've made a mistake. My version is 3.0 but not 3.0.1.
> org.apache.commons.net.ftpFTPClient, file will not be totally transferred.

> Key: NET-417
> URL: https://issues.apache.org/jira/browse/NET-417
> Project: Commons Net
> Issue Type: Bug
> Components: FTP
> Affects Versions: 3.0.1
> Environment: Windows XP FTPClient program sending file to Windows
> 2003 IIS FTP Server
> Reporter: tom yang
> Labels: newbie
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> If I use this ftp.storeFile(f.getName(), stream) to transfer file to the FTP
> Server. After the function returned the file will be partially sent.
> E.g. If the file has 1025 bytes, only 1024 bytes will be sent while if the
> file has 2050 bytes, only 2048 bytes will be sent.
> That's because the default buffer size is 1024, each time 1024 bytes of file
> content will be sent to the FTP server. But stream.flush() is not called at
> the end of each transfer. Finally, socket stream to FTP server will be closed
> before the
> last transmission and the last frame of data, which may be less than 1024,
> will be left unsent.
> My way of fixing this BUG: Change the content of method
> FtpClient.__storeFile(), change the last parameter for calling
> Util.copyStream() to 'true'.
