Selecting Documents allows you to add documents for transfer to your iPod. You can add any Word, RTF or text document for transferring to your iPod. You can also add a folder, in which case each document within the folder is transferred to your iPod.
You can add items either by using the add button or dragging and dropping the document/folder into the document list. Note that if the document is already present the new document is ignored and the current entry is highlighted to indicate that it is present.
