folder name is required

Error message

folder name is required

What it means

Raised in validateFolderName (used by CreateFolder and RenameOrMoveFolder) when the trimmed folder name is empty. A folder name must be a single tree level — blank names and later also separator-carrying names are rejected. Input-validation helper.
