To Display a Folder

You can display the contents of a folder in any of the following ways:

Double-click on the folder in the view pane.
In the Location field, type the path of the folder that you want to display, then press Return. The Location field includes an autocomplete feature. As you type a path, the file manager reads your file system. When you type enough characters to uniquely identify a directory, the file manager completes the name of the directory in the Location field.
Use the Tree in the side pane. For more information, see Using the Tree From the Side Pane.
Use the Back toolbar button and the Forward toolbar button to browse through your navigation history.

To change to the folder that is one level above the current folder, choose Go -> Up. Alternatively, click on the Up toolbar button.

To reload the display, click on the Reload button.

If you cannot find the folder that you want to display, you can use Search Tool. To start the Search Tool, click Launch, then choose Find Files.

Using the Tree From the Side Pane

The Tree displays a hierarchical representation of your file system. The Tree provides a convenient way to navigate your file system. To display the Tree in the side pane, choose Tree from the drop-down list at the top of the side pane.

In the Tree, folders are represented as follows:

Folder State	Graphic Representation
Closed folder	Right arrow
Open folder	Down arrow

Table 5–2 describes the tasks that you can perform with the Tree, and how to perform the tasks.

Table 5–2 Tree Tasks


Task	Action
Open the Tree.	Choose Tree from the drop-down list at the top of the side pane.
Close the Tree.	Choose another item from the drop-down list at the top of the side pane.
Open a folder in the Tree.	Click on the arrow next to the folder in the Tree.
Close a folder in the Tree.	Click on the arrow next to the folder in the Tree.
Display the contents of a folder in the view pane.	Select the folder in the Tree.
Display the contents of a file in the view pane.	Select the file in the Tree.

You can set your preferences so that the Tree does not display files.

Opening Files

When you open a file, the file manager performs the default action for that file type. The default action can be one of the following:

Use a viewer component to display the file in the view pane.
Launch an application that opens the file.

The file manager checks the contents of a file to determine the type of a file. If the first lines do not determine the type of the file, then the file manager checks the file extension.

If you cannot find the file that you want to open, you can use Search Tool. To start the Search Tool, click Launch, then choose Find Files.

Viewing Files in the View Pane

The file manager contains viewer components that enable you to display particular types of file in the view pane. For example, you can display the following types of files in the view pane:

Plain text files
PNG files
Joint Photographic Experts Group (JPEG) files

To reload the contents of the view pane, choose View -> Reload. To stop loading an item in the view pane, choose View -> Stop.

When you display a file in the view pane, the viewer component might add menu items to the file manager menus. The menu items relate to the file type that is displayed. For example, when you display a PNG file, the Edit menu contains flip and rotate menu items.

Also, when you display some types of file in the view pane, you can use the file manager zoom buttons to change the size of the item.

To Execute the Default Action

To execute the default action for a file, double-click on the file. For example, if the default action for plain text documents is to display the file in a text viewer. In this case, you can double-click on the file to display the file in a text viewer.

You can set your file manager preferences so that you click once on a file to execute the default action.

To Execute Non-Default Actions Using the Open With Submenu

To execute actions other than the default action for a file, perform the following steps:

In the view pane, select the file that you want to perform an action on. Choose File -> Open With. The Open With submenu opens. The items in this submenu correspond to the contents of the following parts of the File Associations preference tool:
- Default action drop-down list in the Edit file type dialog
- Viewer component drop-down list in the Edit file type dialog
Choose an action from the Open With submenu.

To Execute Other Actions When Displaying a File

When you display a file in the view pane, the side pane might contain buttons.

The buttons represent any actions that are defined in the File Associations preference tool. The actions are defined in the Default action drop-down list in the Edit file type dialog in the File Associations preference tool. Click on a button to execute an action. For example, if an action defined for plain text documents is to open the file in the gedit text editor. If this action is defined, an Open with gedit button is displayed in the side pane. To open the file in the gedit application, click on the Open with gedit button.

Note –

A button that represents the action does not appear in the side pane if the actions are excluded in either of the following dialogs:

Open with Other Application
Open with Other Viewer

To Open Locations

The file manager provides an integrated access point to your files, applications, FTP sites, and URIs.
