To Set Optional ACL Default Entry Types

In File Manager, select the icon of the folder for which you want to set an optional ACL Default entry type.

Choose Properties from the File Manager Selected menu or from the icon's pop-up menu (displayed by pressing Shift+F10 or mouse button 3).
The Permissions dialog box appears.

Click the Show Access Control List button if the folder has no ACL defined.
If the folder has an ACL defined, it will be visible when you open the Permissions dialog box.

If the ACL does not contain the required default entries, they will also be created, with permissions set to no-read, no-write, no-execute.

Click the Permission check boxes to set the permissions for the Default entry.

Click Add in the Add Access List Entry dialog box.

Continue to add as many ACL entries of type Default User or Default Owning Group as you want.

Use the Apply Changes To option button to choose the scope of the changes.
The options are This folder only (default) and This folder and its Subfolders.

Click OK to apply the current settings and dismiss the dialog box. Click Apply to apply the settings without dismissing the dialog box.

Permissions Mask

ACL-enabled files and folders have a mask defined whose default permissions are the group permissions for the file or folder. The mask is the maximum allowable permissions granted to any user on all ACL entries and for Group basic permissions. It does not restrict Owner or Other basic permissions. For example, if a file's mask is read-only, then you cannot create an ACL with write or execute permission for a user without changing the mask value.

Use the mask as a quick way to limit permissions for users and groups.

To Modify the Mask

In File Manager, select the icon of the file or folder whose mask you want to modify.

Choose Properties from the File Manager Selected menu or from the icon's pop-up menu (displayed by pressing Shift+F10 or mouse button 3).
The Permissions dialog box appears.

Click the Show Access Control List button if the folder has no ACL defined.
If the folder has an ACL defined, it will be visible when you open the Permissions dialog box.

Select the Mask entry in the Access Control List Permissions scrolling list.
The current mask permissions appear in the Effective column.

Click the Change button.

Click the Permission check boxes to reflect the values you want for the mask.

Click the Change button in the Change Access List Entry dialog box.

Use the Apply Changes To option button to choose the scope of the permissions changes.
For files, the options are This File Only (default), All Files in Parent Folder, and All Files in Parent Folder and its Subfolders. For folders, the options are This folder only (default) and This folder and its Subfolders.

Click OK to apply the current settings and dismiss the dialog box. Click Apply to apply the settings without dismissing the dialog box.

Using File Manager Objects on the Desktop

The desktop lets you put any file or folder icon directly on the backdrop of the current workspace for quick access. Any icon you drop on the desktop stays where you put it.

File Manager provides a way to view all the objects in your file system. However, the object is only visible when you are viewing the folder it is in.

To make an object more accessible, you can put it directly on the workspace backdrop. The desktop is that area or surface on which windows appear to lie. When an object is placed there, it is called a workspace object. There is a separate desktop for each workspace.

Placing an object on the workspace does not alter the original file or folder. In fact, the icon that appears on the workspace is really just a shortcut for accessing the real file or folder. Any operation you perform on the workspace object is actually performed on the file or folder it represents.

Workspaces in the Desktop

You can have several workspaces on your desktop, so you can set up your working environment by putting the files and folders in the workspaces where you use them most, or in more than one workspace if needed.

Pop-up Menus

Each workspace object has its own pop-up menu, displayed with mouse button 3 or by pressing Shift+F10 when the icon is selected. This menu contains commands for manipulating the object, including all the actions that appear in the File Manager's Selected menu when the object is selected. The Workspace pop-up menu is similar to the pop-up menu available within File Manager windows, but contains a few different commands.

To Put a File or Folder on the Workspace Backdrop

This procedure creates a copy of the icon on the workspace backdrop. Any changes you make to the copy on your workspace backdrop will also be made to the original that is still in File Manager.

Switch to the workspace where you want to display the object.

Then:
- Drag and drop the object's icon onto the workspace.
- Or, select the icon, then choose the Put in Workspace command from the Selected menu or from the icon's pop-up menu (displayed by pressing Shift+F10 or mouse button 3).
You can repeat these steps to put an icon on the desktop in as many workspaces as you want.

To Display the Pop-up Menu for a Workspace Object (Mouse)

Point to the object's icon.

Press mouse button 3.

Choose a command from the menu by dragging to the command then releasing the mouse button.
