File Structure Also Called
Directory Structure File System
Dos/Linux/Mac –all must use file structures to store and access the data.
Even the internet uses very similar file structures.
Computers can contain millions of files
Nearly all should be stored in folders. ALL user files should be stored in folders
Organizing Think of each drive as a very big filing
cabinet. One in which everything can easily be sorted.
In order to find things, they should be named with meaningful names, and they should be put into folders with meaningful names.
Folders Represented by Icons
