It makes no sense to use this to download single large file. SSH compression has the same effect.
But it can improve the performance significantly, when downloading lot of smaller files.

You probably use WinSCP.exe 5.16 but not compatible WinSCPnet.dll.
I'm sending you a download link.

But anyway, this all is too complicated, both extensions and automation scripts, especially with the powershell popup window. ...

Because there's too many things that can be different on different systems. And no way I'm adding zillion options to cover them all. With a script, everyone can modify it according to his/hers needs.

Thanks, but it didn't work for me. The error message is about

Error: Exception calling "ParseUrl" with "1" argument(s): "SSH host key fingerprint "ssh-rsa-..." does not match pattern ...

But anyway, this all is too complicated, both extensions and automation scripts, especially with the PowerShell popup window. I don't understand why have those - actually, WinSCP can do it all already, and it could do it long ago, but not in one command/click - in 3 or more. I already have toolbar buttons that tar/bzip and tar/gz and so on, also, respective buttons for unpacking. The only thing that is missing - some kind of macroses that allow to run multiple commands at the same time, and the commands should be able to run ON DIFFERENT SIDES (both remote and local).

And archive name should not be entered, it's a temporarily file that should be deleted after unpacking; I should not even see it or know it was there. The real archive name should be something temporary and opaque that doesn't exist in both panels.

The user only has to configure exact commands for packing/unpacking on both sides.
For example, it could be, for downloading:
1. tar -cvj -f arc-tmp-zzz.tbz -- !&
2. "c:\Program Files\WinRAR\WinRAR.exe" x !^!

So, a prospective "Download with compression" button would run the 1st command on whatever is selected on the server side, creating arc-tmp-zzz.tbz, then the archive is downloaded like I double-clicked it, then it is removed from the server, and then the 2nd command would run on arc-tmp-zzz.tbz and the archive is deleted.

The whole thing should work just like downloading with double-clicking, with the only visible difference that the download is faster.

This is now implemented:
https://winscp.net/tracker/1773
https://winscp.net/eng/docs/extension_archive_and_download

The extension will be included in 5.16, but you can manually install it to the current 5.15.
https://winscp.net/eng/docs/ui_pref_commands#extensions

You can also extract the files with unrar or unzip.

I have realised that you cannot do this with custom commands yet.
I have filed an improvement to allow this. Also I have written guide for accomplishing this using scripting.

Ok, thanks.

No you cannot, though you can setup a custom command that executes the script for selected files. I'll try to write a guide for that.

Ok, I read the comments, I tried enabling SSH compression but that just didn't change anything - the number of transferred bytes and the speed are the same. Perhaps compression should be enabled at the server.

That's great! :wink:

Thanks for your post. This request has been added to tracker.

Hi.

Is it possible to set up autopacking downloaded files? For ex., before downloading, run

for the selected files, then do download the , then transparently unpack it (or maybe leave as is) with a chosen (local) program.
Both remote and local commands should be configured.
I see it as an extended custom command that applies both remotely and locally.

Point is I do the thing too often manually (pack - download - unpack).
