If you move a file, the metadata follows it. if you detete a file, the metadata is automatically deleted. Metadata (or extended attributes) are used to store information that is relatd to the file but is not part ofthe file itself. For instance you have a plain text file and you store the Author's name in a extended-attribute so you can have this information available without having to edit the contents of the file. Image thumbnail is another example. BeOS comes with a text editor (StyledEdit) that lets you write text files using simple text formating (changing fonts, colors and font size of parts of the text) but after you save it you can open the file in an standard text editor and although you will not see the special formatting you did, there wll be no garbage in the file, only the text itself. All formating information is saved as an attribute. -Bruno
