As the size of hardrives increase, more people are using partitions to seperate and store groups of files.
Windows XP uses the C：プログラムファイル directory as the default base directory into which new programs are installed. However, you can change the default installation drive and/ or directory by using a Registry hack.
走る the レジストリエディター （regedit) and go to
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersion
Look for the value named ProgramFilesDir. by default,this value will be C:Program Files. Edit the value to any valid drive or folder and XP will use that new location as the default installation directory for new programs.
