In ECMap, while information is logically organized in projects and maps, it is physically organized in a directory/file/record structure or a database/table structure. Files are located in directories and subdirectories. Directories are sometimes referred to as folders, and certain directories are called mailboxes. A mailbox is a directory that is used for the pickup and delivery of data that has been mapped or will be mapped.
In ECMap, directories and files are separate data objects. A file does not need to be associated with a directory in order to exist. This provides great flexibility in defining file-based application data. One directory can have a number of files, and many directories can include the same file.
