File size transferred for large file is way over the original size

[Erik Johansson]

TECHNICAL INFORMATION
FTP Server: Windows server 2003 R2 x86
Client operating system: Windows 7 x64
File Zilla: 3.5.3, Build date: 2012-01-08
Server and client filesystem: NTFS
Connection: VPN tunnel using native windows client to ISA 2006 server running on Windows 2003 R2 x86 with shared key L2TPipsec connection.
FileZilla set to transfer binary file.

FILE INFORMATION
File type: VMware vmdk file.
Server side size using Windows Explorer: 2,687,200 KB
Server side size using Windows 7 native FTP client: 2,751,692,288
Server side using filezilla: 2,751,692,288

TRANSFER INFORMATION:
Size of transferred file using filezilla interface: 4,636,080,127
Size of transferred file using Windows cmd: same

DESCRIPTION:
The file size is reported correctly by FileZilla. Starting the transfer by dragging the file to the client window correctly starts the transfer. The time of transfer seems to be correctly reported using the file size and the transfer speeed (as displayed). When the progress window reaches the original file size, it reports zero time left. However, the transfter continues and in the case creates a much bigger file.

To me this seems like some kind of bug.

This looks like a duplicate of #7834.

Can you please provide logs? Did the download resume or does the problem happen without resuming?

[Alexander Schuch]

As you are using IIS, this might be a duplicate of #4672 if you are resuming an aborted download.
