FoldersWhen there are a lot of data items to be managed, it makes sense to divide them intosmaller sets. A folder is a place where a set of items can be collected. A folder can bepresent among single items in a directory, but it can be opened in order to view itscontents. Users are able to create folders and delete them, move items into foldersand out of folders, and rename folders and change other properties of folders(depending on application).In Series 60 UI, hierarchical folder structures are not allowed. In other words, a foldercannot reside inside another folder.The normal methods for managing folder are as follows:To create a new folder, the user selects the New folder option while in a dataitems list.To add items into an existing folder, the user selects the Move to folder optionwhile the focus is on the item to be moved. A list of existing folders is offered,and the user can select the target folder. (To add more than one item at a time, itis possible to mark items using the marking feature.)The functions for folder managing (Move to folder, New folder) are available in asubmenu called Organize.GroupsGroups are another means of managing data in a container. But unlike folders,groups do not contain actual data – there are only links to data that exist elsewhere.This makes it possible to access the same data from many places. A typicalapplication for groups is a distribution list: one can collect a set of addresses intoone group, to send messages to all the addresses by just referring to the group, andthe same addresses can be present in any number of different groups.Groups can be managed in much the same way as folders. There are somedifferences, however:Groups are presented in a separate group view, not within the actual data itemslist. The group view can be a tab view within the application.To create a new group, one goes to the group view and selects the option Newgroup.To add items to a group, one must be within the target group view, and selectthe Add items to group option there. A list of items is then presented, typicallyas a multiselection list, for the user to choose from.82
