Change the Default Directory of Software Installation
You may want to change the location of your system default folder (C:\Program Files) from C drive to
another system drives (D or E drive). By default software setup will attempt to install program in
C:\Program Files directory. It is good practice to make the backup of the installed programs, if you
installed all your programs in other than C drive. If you have little knowledge about editing
windows registry then you can configure your computer for this purpose.
Follow the given steps to configure windows registry:
1. Click on Start button then type Regedit in Run option.
2. Here navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
3. In right side panel, double click on ProgramFileDir.
4. Now modify the value to any other drive (for example D:\Program Files).
Now close the registry editor and restart your computer after any changes to go into effect....
The UNIX filesystem is laid out as a hierarchical tree structure which is anchored at a special
top-level directory known as the root (designated by a slash '/'). Because of the tree structure, a
directory can have many child directories, but only one parent directory. Fig. 2.1 illustrates this
layout.
To specify a location in the directory hierarchy, we must specify a path through the tree. The path
to a location can be defined by an absolute path from the root /, or as a relative path from the
current working directory. To specify a path, each directory along the route from the source to the
destination must be included in the path, with each directory in the sequence being separated by a
slash. To help with the specification of relative paths, UNIX provides the shorthand . for the
current directory and .. for the parent directory. For example, the absolute path to the directory
play is /home/will/play, while the relative path to this directory from zeb is ../will/play.
