You set the following options in the Saving Files set of the Output Settings dialog box:

File Naming

Choose elements from the pop‑up menus or enter text into the boxes to be combined into the default names for all files. Elements include document name, slice name, rollover state, trigger slice, file creation date, slice number, punctuation, and file extension. Some options are relevant only if the file contains slices or rollover states.

The text boxes let you change the order and formatting of the filename parts (for example, letting you indicate rollover state by an abbreviation instead of the full word).

Filename Compatibility

Select one or multiple options to make the filename compatible with Windows (permits longer filenames), Mac OS, and UNIX.

Put Images In Folder

Specifies a folder name where optimized images are saved (available only with documents containing multiple slices).

Copy Background Image When Saving

Preserves a background image that has been specified in the Background preferences set.

Include XMP

Includes any metadata file information that was added to the document (choose File > File Info to view or enter document metadata). Metadata is fully supported by JPEG file formats, and partially supported by GIF and PNG file formats.
