15.7 Backing Store Management
This is a task of the OS. In particular the OS must manage:
- Access methods
- Files
- Free Space
In deciding where to place a new file there are two strategies.
15.7.1 Directory Structure
When backing store media are capable of holding more than a few files, it is
common to organise the files into directories.
These directories can then be organised into a hierarchical (or tree)
structure.
Some operating systems (not DOS) give access rights to all the levels above
a particular user.
