# Displaying the Thumbnail of a Protected Document

When you open Desk, a padlock mark appears on the page of a protected document. You cannot view the contents of the page in this state. The number of pages and paper size are hidden as well. To manipulate a protected document in Desk, you must first display its thumbnail.

## Using a password

Change the workspace of Desk to the thumbnail view and do as follows.
Procedure
1.
Select a document protected by a password, select [Security] from the [Document] menu, then select [Display Thumbnail].
The [Password] dialog box appears.
2.
Enter the password to open the document in [Open password]. Specify whether to temporarily store the open password, then click [OK].
The thumbnail of the protected document is displayed.
If you have selected [Store this password temporarily], DWSPswd starts and a corresponding icon appears in the notification area on the right side of the task bar.
Note
If the open password is not specified for the protected document or if its open password is temporarily stored, the thumbnail is displayed without requiring you to enter the password.

## Using an Electronic Signature

To display the thumbnail for a document protected by an Electronic Signature, you must prepare an Electronic Signature and an Electronic Signature Case as follows:

- The Electronic Signature specified as being capable of opening the protected document must be placed in the [My Signature] tab of your Electronic Signature Case.
- The Electronic Signature Case mentioned above must be open.

If the Electronic Signature Case is not open when you try to display the thumbnail, the Electronic Signature Case Tool automatically starts and prompts you to enter the password. Enter the appropriate password to open the Electronic Signature Case.
