Resource filesystem, as the editor sees it. This object holds information of all resources in the filesystem, their types, etc. [b]Note:[/b] This class shouldn't be instantiated directly. Instead, access the singleton using [method EditorInterface.get_resource_filesystem]. Returns the resource type of the file, given the full path. This returns a string such as [code]"Resource"[/code] or [code]"GDScript"[/code], [i]not[/i] a file extension such as [code]".gd"[/code]. Gets the root directory object. Returns a view into the filesystem at [param path]. Returns the scan progress for 0 to 1 if the FS is being scanned. Returns [code]true[/code] if the filesystem is being scanned. Reimports a set of files. Call this if these files or their [code].import[/code] files were directly edited by script or an external program. If the file type changed or the file was newly created, use [method update_file] or [method scan]. [b]Note:[/b] This function blocks until the import is finished. However, the main loop iteration, including timers and [method Node._process], will occur during the import process due to progress bar updates. Avoid calls to [method reimport_files] or [method scan] while an import is in progress. Scan the filesystem for changes. Check if the source of any imported resource changed. Add a file in an existing directory, or schedule file information to be updated on editor restart. Can be used to update text files saved by an external program. This will not import the file. To reimport, call [method reimport_files] or [method scan] methods. Scans the script files and updates the list of custom class names. Emitted if the filesystem changed. Emitted if a resource is reimported. Emitted if at least one resource is reloaded when the filesystem is scanned. Emitted if the source of any imported file changed.
