The Filecabinet, file folders, and files are objects that store data in your AT&T FACE Office. These objects are accessible through the Office item on the AT&T FACE menu. When you select Filecabinet from Office menu, a frame opens that lists the contents of your $HOME directory. The frame will be labeled with the name of your home directory. The contents are file folders or files. File folder objects are the containers for your files. FACE uses file folders and files just as a regular office would. Titles for file folders are the names of the UNIX System directories they represent. File folders can be created, deleted, redescribed, or renamed, by using keyboard keys or commands. Deleting a folder will also delete any files or file folders contained within it. File objects are the containers for your work. Files contain information much like pieces of paper do. Excluding the exceptions noted above, a file object can be created, copied, deleted, moved, opened, redescribed, renamed, and have its security (i.e., permissions) changed. There are many varieties of files and the way you use them differs according to the type of information you store in them. The different types of files will be discussed later. When you move the cursor to a file or file folder in the Filecabinet, or any other file folder, a new frame will open filled with the contents of the object. A frame for a file folder will contain a list of file and file folders. The action on a file depends on the type of file: Standard File: Contains an ascii text document. When you open a Standard File your default editor will be invoked. Foreign File: This type file can be copied, renamed, moved, etc. but cannot be viewed or edited. It is usually a file from another computer system that is incompatible with the UNIX operating system. Typically, a user would want to store this type of object only temporarily before transferring it to the appropriate computer system. Data File: This type of file's contents are in binary format, which can not be viewed, printed or edited. It can be copied, moved, deleted, etc. Executable: This type of file will contain a computer program. Opening this type of object will execute or "run" the program. The screen clears and the output of the program is displayed and you must press ENTER to continue FACE. You can change the way objects in a folder are displayed (order of presentation and amount of information) by using the organize command for an individual file folder, or by using preferences/folder options for your entire Filecabinet and Wastebasket. When assigning an object name to a Filecabinet or file folder object you are creating or renaming, it must be one word with a maximum of 12 characters. The following special characters are not allowed when naming objects: ! @ # $ ^ & * [ ] ( ) { } < > ? / | " ' ` ;. The following characters may be used in object names, but not as the first character: . + -. By using the security SLK command (permissions) you may control who has access to your files and file folders. This allows you to determine who has Read, Write, and Run/Search permissions for yourself, your group and anyone with access to the system.
