If applicable, configure folders under the project root by selecting the relevant folders and clicking the toolbar buttons. Alternatively, you can do it later in the Directories page of the Project Settings dialog box.
|Project Root||Click this button to make the selected folder the project root.|
|Excluded from Download||
Click this button to have PhpStorm skip the selected folder under the project during download.
These can be sources that you should not update at all, media, caches, temporary files, that you
actually do not need in your work.
Exclusion is applied recursively. This means that if the selected folder contains subfolders they are automatically marked as excluded as well.
|Resource Root||Click this button to enable PhpStorm to complete relative paths to resources under the selected folder.|
|Excluded from Indexing||Click this button to have PhpStorm completely ignore the selected directory during indexing, parsing, code completion, etc.|
