# [Common] tab [Process Pages] dialog box

Use this tab to specify the settings for image page processing common to all types of pages.

### [Add/Delete thumbnail data]

Adds or deletes thumbnail information on all pages. If you delete thumbnail data from each page, the file size becomes smaller. However, it takes more time for Desk to display thumbnails.
By default, this box is cleared.

- [Add]
  Adds thumbnail data of all pages to a file.
- [Delete]
  Deletes thumbnail data from a file. However, if it takes too much time to display the thumbnails, you may not be able to delete the thumbnail data.

Note
For a document with the thumbnail deleted, the thumbnail information will be added to the file automatically if the file is saved after the thumbnail is displayed in Desk or saved after display in a list in Viewer.

### [Delete all annotations]

Deletes annotations from all pages.
By default, this box is cleared.
Note
The fixed annotations are also deleted with this command. Header and footer will not be deleted.

### [Delete all original data]

Deletes all the original data attached to the DocuWorks document.
By default, this box is cleared.

### [OK]

Click this button to create a DocuWorks file according to the settings.
Even if no setting is made, the document will be recreated. As a result, the file size of the document may become smaller because of optimization.
