I am using the current version of Winscp, 5.7.3 and transfering files using FTP with TLS/SSL Explicit encryption. Transferring smaller files, many of them just under 800 bytes and finding most arrive as 0 byte files on the server. This happens both with the GUI and the .net component (ultimately would love to send them using .net but found it happens on GUI as well so if that works maybe both will), happens whether I am trying transfer as text or binary.
Appears this was a bug on some earlier Winscp versions, so I tried to upgrade first to 5.7.3 but finding the same behavior. Tried the transfer in another product Filezilla using FTP and did not encounter the 0 byte issue, though I could find no significant difference in the settings.
If you have any info or recommendations let me know. I really appreciate any help.
