put *.* with append

I'm trying to make a script that PUTs all files in a directory onto the server. The basic script works OK when the destination files don't exist (which they usually won't). However, when the file does already exist remotely I would like the local file to be appended to the existing remote one. And then afterwards, the local file is deleted. This is what I've got at present:


But this overwrites the existing files regardless. I guess it's probably because I need to state a target for the append flag to work, but how do I do that with *.*? The filenames will be different every day so I can't specify what the target name is, other than the same as the source file name.

Can this be achieved fairly easily? The alternative, not so automated, is to script it to check for existing files and decline to carry out the put command.

I've done more testing and it doesn't appear to be related to the use of a wild card *.*. Even with the following command:


It still overwrites the destination, rather than appending to it. The delete parameter works as expected though. I've looked in the winscp log file, but can't see anything obvious there, not totally sure what I should be seeing there though. I've updated to WinSCP 5.6.2 just in case, but it hasn't made any difference.

Could it be the sftp server (freeFTPd) not compatible with the append function, or is it implemented entirely on the client side?

What protocol are you using? The -append works with SFTP only.
See https://winscp.net/eng/docs/scriptcommand_put

It works first the file mask too.

Yes, I'm using sftp. This is the entire script:

Please attach a full log file showing the problem (using the latest version of WinSCP).

Here's a log file from a recent attempt, I think I've hashed out everything sensitive. I did tweak the put parameters slightly to try and get it to work, but the result is still the same - all files are overwritten rather than appended.

Does the log file give any clues?

I'm wondering if append isn't supported by some sftp servers? I'm using freeftpd/freesshd, and I've also tried SolarWinds sftp server, and both overwrite rather than appending. I notice in the proftpd docs, that resume/append isn't enabled by default, but is an option. So that looks like it should support it, but I don't want to go to great lengths to setup proftpd, just to find that the problem is with my script. :?

I think I've cracked this one - needed to enable resume/transfer for all files in endurance settings.

You are using freeFTPd server, right? It is buggy. It does not fail an attempt to overwrite an existing file with "exclusive" flag set. That makes WinSCP fail to learn that the file already exists, hence it does not append, but override. For the same reason, WinSCP does not display overwrite confirmation prompt in GUI.

Not sure about the exclusive flag, but I've got it working now (with freeFTPd server). I needed to change the endurance settings so resume was enabled for all files (mine were all below the size threshold).

I am using the below script to transfer the file using SFTP with append feature. The file is getting transferred but the file has been overwritten every time. I am using free version of 'Core FTP server'. Any help would be appreciated.

option batch on
option confirm off
open "sftp://sftpuser:sftpuser@10.20.17.210" -hostkey="ssh-rsa 2048 6d:f8:a8:e9:cc:05:95:07:16:75:53:65:35:01:2b:2d" -passive=on -timeout=300
option transfer binary
put -resumesupport=off -append "C:\Messages\sample.txt" "/"
close
exit

This is a known bug in Core FTP server. Note that when you try to overwrite an existing remote file, you do not get an overwrite confirmation. It has the same root cause.
