The ServicePackFiles is needed: contains the service pack file versions
for use in preference to ones from the original CD if needed by File
Protection/SFC/New Hardware etc. On an NTFS drive a useful amount of
space can be saved by compressing it. What you can do if you have a CD
burner is burn the complete folder to a CD, then run regedit.exe and at

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup

Change the value of ServicePackSourcePath and ServicePackCachePath in
the right pane to reflect the drive. Best if you have 2 drives, and can
have the original SourcePath on one and this on the other

The uninstall folder you can delete once you are satisfied you will not
want to uninstall. The downloaded files were put into a working folder
- something like C:\long cryptic number - which ought to have got
deleted when installation completed - and expanded to that
Windows - Download one, which is not I think going to be usable again so
you might as well delete that too
