The document number (field 'Document') is characteristic for the document. This is automatically assigned by the system. Each 'Document' consists of a maximum of 640 pages, and each document is automatically assigned to a 'Folder'. This folder number (field 'Folder') is assigned automatically. In short, at the beginning you work with folder number '1', later the folder number is automatically increased by one each time from time to time.
The fields 'Document', 'Pages' and 'Folder' can therefore not be edited. The same applies to the 'Archived' field, which indicates whether a record has already been archived. If it is, no more pages can be added.
The term record is plus/minus equivalent to the term document. A file does not contain multiple documents; a file is equivalent to one document.
