Thanks, Martin, for your fast answer. However, I have some concerns.
I know there is a "get" command which copies the file from remote to the local. But what I look for is to edit multiple files from a list. Is there any such command which would put the file on the remote to the internal/external editor so that I can edit it directly?
I use external editor which allows to open multiple files (notepad ++) in tabs. If I want to edit the files directly on the remote side, I have to browse the path to each one of them and then open by pressing F4. I can make some modifications in all of them at once and save them back on the remote machine. If it is possible doing this with some script, can you give me just a small hint on the command or just a link, as I haven't found it in the commands docummentation, nor here: https://winscp.net/eng/docs/task_edit.
One small note: It would be great to see this as a new feature in the WinSCP GUI environment (where you can put the list of files which would then go to the editor - either external or internal one).
