Successfully uploaded file is larger on remote server than original source file

[Justin Klein]

Running Filezilla 3.3.5.1 on Windows XP 64-bit ("Windows Server 2003 build 3790, Service Pack 2");

Connecting to a vsftp over FTPES;

The majority of the time, file transfers work fine - but what I've found is that periodically when uploading files over poor connections, Filezilla will report that a transfer completed successfully, but it turns out that the "successfully" uploaded file is LARGER (on the remote server) than the original source (local) file!

If, for instance, I upload a directory of 50 images, eventually FileZilla will report 50 successful transfers. However, if I then do a directory comparison of the source and destination, it'll turn out that i.e. 45 of them match in filesize, but 50 of the remote files are LARGER than the source files which were supposedly uploaded.

Can you please provide logs, see ​http://trac.filezilla-project.org/wiki/TicketSubmissionGuide#Logs.

Make sure you upload in binary, and not in ASCII mode. Do the "larger" images still work?

Unfortunately I'm no longer on XPx64 (for over a year now), so I cannot reproduce this bug...
