File downloaded via WinSCP is corrupted
Advertisement
File can be transferred to server correctly. But when file is transferred back to local computer in WinSCP, the file size changes. A log file is attached. Both FileZilla and scp command work without this issue. Could you please take a look? Your help is appreciated.

Looks like the problem has something to do with the file size. There is no problem if the file is smaller than 2M. The log for a good transfer is attached.

Here is another log file. For the first download, the file size changed. The last 2 downloads were good.

Thanks for the logs.
Regarding the first transfer of file
Regarding the first transfer of file
test.dll
: So you can see the file as having 2613760 bytes in a remote panel. And after you download it, it has a different size, right? Smaller or larger? Can we have a copy of the file before and after? Can you attach a log file on level Debug 2?

Thank you for looking into it. Yes, it has a different size. It becomes larger after download. I attached a debug 2 log file. I will send the file in another post.

I believe it's server-side problem.
Here, WinSCP asked for data at position 2587645 (
What is beyond end of file (2587645 + 32755 > 2613760), so the server should return only 26115 bytes. But it did return 26947 bytes (
I cannot explain why FileZilla works, but it can be just a coincidence, due to a different requests sizes that FileZilla can be using.

Thank you so much for investigating this. I will report the problem to the service provider.
