Files options
Autosave frequency Expression Design periodically saves opened files for backup and recovery purposes. This option lets you select how often this is done: Never, Seldom (about every 5 minutes), Normal (about every 30 seconds), or Frequent (about every 5 seconds).
Thumbnail size By default, Expression Design saves your files with a large thumbnail image, which then appears in the Open dialog box when you select the file. You can create smaller thumbnails by selecting Small from the Thumbnail list, or select Off to refrain from creating any thumbnail at all.
Thumbnail image range Which objects should appear in the thumbnail image? You can select among Page frame (which saves only those paths within the document frame), Crop marks (which only saves those paths within your crop mark boundaries, assuming you have set them), or Objects bounding box (which includes every object in your document, even those far off on the pasteboard).
Import When you open an Expression Design document built with an earlier version (such as one of the Community Technology Preview or "CTP" versions) and that file contains features no longer supported or supported differently in the current version, the program can alert you to the fact that some changes to the document can be made. When you select the Create import summaries check box, the program will alert you to which features are being altered upon import. If you don't want to see this report, clear the Create import summaries option. If you select the Show import warning dialog check box, Expression Design will display an alert dialog box whenever you open one of these older documents.
