The problem comes when you try to move the location of the 'Program Files'
folder. If you were move it to, say, your [D:] drive, immediately after
installing XP then it becomes feasible. If you do this any later on, so
many program will cease to function correctly.
You move the default location of the 'Program Files' folder by changing
it's
value specified in the registry under:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion]
"ProgramFilesDir"="C:\Program Files"
...this sets the system environment variable: %ProgramFiles% and
subsequently, any [most] times a new program installs itself, it will (IF
it
asks), will ask you for a location somewhere within this specified
directory.
Also, it does not matter at all if the "%ProgramFiles%" folder is on a
different 'drive' to your system drive.
Programs will sometimes install files in addition to their main executable
files in their named folder within the "%ProgramFiles%" folder, will
place
additional files in the following locations:
"%ProgramFiles%\Common Files"
"%SystemRoot%\system32"
"%USERPROFILE%\Local Settings\Application Data"
"%USERPROFILE%\Application Data"
"%ALLUSERPROFILE%\Application Data"
..as you can see, these other locations are not dependent on what drive
they
are on but are specified with the use of %variables% - no matter what
drive they are on.
While I will agree that *some* programs may require themselves to be
installed on the system drive [C:] most programs will quite happily allow
themselves to be installed into the 'default' "%ProgramFiles%"
directory - no matter where that is. Although, again, changing the
"%ProgramFiles%" folder after programs have been installed there will more
than likely result in them ceasing to work.

Guess it doesn't matter who does what. Stuff gets scattered which means
backup is a nightmare unless you backup the whole drive. Guess that's
the
only answer. The problem of course with that is that if C: gets messed
up, you need several backups at different time increments to protect
yourself from putting the problem right back in.
Can anyone recommend a website that explains this well? I'd love to be
able to backup all the settings from all my programs so when I reinstall
the OS, it doesn't take 10 hours to get everything back to normal. I bet
not 1 in 10 Windows users has any clue about this.
