Incorrect File Size - help please!

Using WinSCP 3.7.1
- transferring from WinXP to Windows Server 2003.
- file size 500Mb approx.
Problem: the transfer seems to go ahead ok, but the reported filesize on the server is:
- always wrong
- not consistent, over several attempts.

If info on config settings required, please advise, and I will post the required info.

Much appreciated

Just read the sticky!.

Using SFTP (V3) and SSH Ver 2.

Thanks in advance

Are you sure you are using binary transfer mode? Also can you try more recent version?

Thanks
1. The Transfer Mode: Automatic
The files are all of type MDB, so force Text as Transfer Mode should not apply (MDB is not in the list).

2. However your response triggered more analyis:
We already have another set-up which successfully handles the transfer of the same files!

Both set-ups use the following:
Client: WinSCP
Ver 3.7.1 (Build 257)
Server: Globalscape Secure FTP server
Ver 2.0.7 (Build 12.20.2004.3)
I appreciate the Server version is is a bit old, but as I said above, it performs fine on another installation with exactly the same files.

The main difference is with the networks....
The traffic at the server end is going through:
(a) a PIX firewall
- this happens on both installations
(b) a Content Server Switch (ie a Load Balancer)
- this does NOT occur on the working installation.....

Possibly this last factor is a big clue, but I would welcome your guidance.

Thanks in advance

You will see actually used mode on transfer progress dialog.

I do not think it is the reason of the problem.

Well, I did it again, with compression on, this time.
Everything SEEMED to go smoothly, but:
The orginal file size was: 622,415,872
The received file size was: 404,340,736

Finally, I downloaded the previously uploaded file, and the filesize was knocked down to 64Mb this time!

Any further suggestions?
TIA

Can I have a test account on your server?

Martin
Thanks for your generous offer, but there's no way this organisation would let you at it - they'd rather lose the service! My apologies.

We are using an old version of Globalscape Secure FTP server, which looking at their version history, had "stability issues" with Win Server 2003...
Our next plan of attack is to upgrade to the latest version - hopefully that may clear it.

Thanks for your support.

Loaded latest version of server-side software - no difference whatsoever.

Any other suggestions anyone?
TIA
