Hidden Workbook Files and Folders
Hidden Files and Folders in the Workbook Navigator
Non-Hidden Items Inside Hidden Folders
To hide files in the workbook:
In the Workbook Navigator tree, right-click on the file or folder that you want to hide.
From the context menu, select Hide. The file or folder is now hidden.
To unhide files in the workbook:
In the Workbook Navigator tree, right-click on the file or folder that you no longer want to hide.
From the context menu, clear the check beside Hide. The file or folder is now visible.
Note: You can display hidden files and folders in Show Hidden Content mode.
To enable Show Hidden Content mode:
Right-click anywhere in the Workbook Navigator palette, or select Workbook Navigator from the View menu.
Select Show Hidden Content. You can now see files or folders marked as hidden.
Hidden folders may contain non-hidden items. Since these items are not hidden they will show up in search results. This may be desirable in some cases, however if this not your intent, then you should hide all the contents explicitly.
The ability to hide content in the Workbook Navigator is only intended to reduce clutter in the navigator. It is not intended to block or restrict the user from accessing content.
