The "name" is not valid as a file or folder name

[vitorolopes]

Type: Bug

Everytime I try to create a file whenever I type the "." before file extension the following message pops up: The "name" is not valid as a file or folder name. Please choose a different name.

When I try to create a folder that error message does not pop up but the folder is not created.

If you use Windows Explorer to create or rename a file and enter a name ending with '.', that character is ignored.

I think the message VS Code displays under the file-rename field is intentional. You should either omit the dot or follow it with some more characters.

I also get that message when creating or renaming a folder if II end the name with a dot.
