2. F ILE MANAGEMENT - WHY IT IS IMPORTANT Why is File Management important? It helps for Jackie and Cable Ties Ltd to stay organised, so that information can be located by her or any other authorised person. Setting up a good structure with sensible file names saves time in the long term. A sensible file name is a name that best describes the information that is contained in the file.

3. F ILE MANAGEMENT - WHY IT IS IMPORTANT Naming Conventions Jackie has created a FILE called New_Clients_April 17 th 2014_V1.docx This shows that the file is called New Clients and that it is Version 1 and the date shows the time when Jackie last updated the file without having have to open it. Now Jackie needs to create a FOLDER to store the file or document.

4. F ILE MANAGEMENT - WHY IT IS IMPORTANT FOLDERS A FOLDER is a container for storing files. A SUB-FOLDER is a folder within a folder. This may be CLIENTS, TECHNICIANS, EQUIPMENT etc FILES Jackie knows that the folders must be understandable to others. A file is the name given to every document that you save on your computer such as word processing, spreadsheet, databases or images. They all have different file extensions for example docx, jpeg. Jackie when she saves her work she saves it in her normal file type e.g. word processing will be.docx AND as a PDF so that the formatting and features will not be lost.
