High text compression in iSilo format documents results in a 50 percent to 60 percent decrease in size. Hyperlinks make it much easier to navigate through a document; images add visual richness to documents, especially photo-quality color pictures. Tables allow the display of tabular data. Formatted text gives style to text for controlled emphasis. VFS support allows you to store and access documents on high-capacity removable storage.
