[Setup]: AppendDefaultDirName

Valid values:

Default value:

yes
Description:

By default, when a folder in the dialog displayed by the Browse... button on the Select Destination Location wizard page is clicked, Setup automatically appends the last component of DefaultDirName onto the new path. For example, if DefaultDirName is {pf}\My Program and "Z:\" is clicked, the new path will become "Z:\My Program".

Setting this directive to no disables the aforementioned behavior. In addition, it causes a Make New Folder button to appear on the dialog.
