Hello and welcome to Advanced Installer forums,
Thank you for your interest in Advanced Installer.
In order to create a
new folder in "Files and Folders" view you can use the [ New Folder ] toolbar button, the “New Folder” tree/list context menu item or press the "Insert" key while the tree control is focused.
Also, if you want the related directory to be always created on target machine, then from its context menu choose "Properties..." option. Then, in the "Edit Folder" ->
"Properties" tab check "Create folder on target machine" option.
If you have any questions let us know.
All the best,
Daniel
