FTP copying size issues

I have been FTP copying files today from Ubuntu Lucid Lynx to Windows 7 x86. This hasn't happened just the once. Sometimes it works OK.
I witnessed the complete transfer and then a second or to after the transfer the file size reduced to about a tenth.
The FTP logs show the complete transfer - see the attached image.

I am using:
Directory Opus Pro 10.5.0.0 (4779) x86
OS 6.1 (B:7601 P:2 T:1) SP 1.0 "Service Pack 1"

I am using custom port 3951

Any ideas?

[s]What does the FTP log say the size transferred was? There should be a line like this in the log:

598827 bytes sent in 9.454 seconds (61.536 Kbytes/sec)[/s]

(Edit: Just realised the screenshot had the log at the bottom, I just hadn't scrolled the screenshot down.)

If the size the log says was transferred is smaller than what you expect (which is the case in your screenshot, I think; it's showing about 4MB transferred instead of 44MB), the FTP server may have transmitted less data than it said it would. FTP downloads will pre-allocate space for the expected size, then truncate the file if less data arrives in the end.

If the size in the log is what you expect, try disabling your virus scanner in case it is modifying the archive after it is written. (That probably doesn't apply here.)

It might be worth checking if other FTP software has similar problems, in case the issue is with the server/firewall/network somewhere.

(Reply above edited, after realising I didn't look at the full screenshot.)

Hi Leo,

I have just tried using FileZilla and that worked fine first time and appeared much quicker too.

When I was transferring with Dopus I was refreshing my receive pane and that was gradually incrementing the size if that makes any difference to your response.

FileZilla log:
