"404 Not Found" means that some URL component could not be resolved. Thus, you should look at the URL (sometimes missing permissions are mapped to "Not Found" as well). Especially, you should compare the URLs for "transfer to Zope" and "transfer to Plone" (I do not understand those terms).
This is major information. For WebDAV access, you must typically use the so called "WebDAV source port". While WebDAV works over HTTP, it requires different handling compared to "normal" browser access. E.g. browser access would typically use cookie based authentication while WebDAV use HTTP authentication, and browser access likely includes navigation around the main content while WebDAV access wants the raw content. Using a special port for WebDAV access allows to distinguish the two access types.
I do not use Windows, but is it possible that the file (you just edited) buildout.cfg is NOT in the folder c:\Users\Username\Plone\ but in the folder c:\Users\Username\Plone\zinstance\ ? (or \zeoserver ). If that is not the case, maybe you need to change the permissions
Hello,
In fact the "buildout.cfg file is in the folder
"c: \ Users \ Username \ Plone \ zinstance ".
On the other hand, the executable "buildout.exe" is in the folder
"C: \ Users \ Username \ Plone \ py-3.8.9.final.0 \ Scripts"
A priori everything went well.
However when I try to transfer files from my local computer to plone to a folder (directory) in plone,
I have a prompt which asks me for a password corresponding to the user (manager) connected.
When I enter the password,
I have the "404 not found" error.
I'm just trying to transfer a few htm files.
WinSCP offers several tools. I select WebDAV.
The window on the left allows me to access files and folders locally on my computer.
The window on the left is connected to plone which in this case is installed on the same computer.
This is why I am using the IP 127.0.0.1.
Thanks for the suggestion.
I had already tried with cyberduck, but the result was no better. I have tried other WebDAV clients, to no avail.
I wonder where it blocks ....
