Files that can be cleared away under c:\windows

I installed my Win XP SP3 into c:\winxp3   (instead of the usual c:\windows).

Can the following files be cleared away as the disk space on this laptop
is rather small :

a) refer to attachment 1 : c:\winxp3\$Ntuninstall*   directories
    what are these directories for & can they be cleared away?

b) refer to output below : can these directries be cleared away?
     Directory of C:\WINXP3\SoftwareDistribution

You can remove the Ntuninstall ones, but that will eliminate the possibility to uninstall any hot fixes.... That's what those are there for.... If anything cut them to an external drive for safe keeping, should u need to remove a kb hotfix....

Softwaredistribution is a store where windows auto updates stores the updates. When this die is cleared/renamed, it rebuilds....

Use this also to find what's storing data....

Few other tips....

Lower the amount of space for System Restore
Disable Hibernation. This could save you several gigs....

Thanks chaps.  So c:\winxp3\SoftwareDistribution  can be safely removed?

What about the following :

C:\WINXP3\$hf_mig$>dir/s |more
 Volume in drive C has no label.
 Volume Serial Number is AC21-92AC

"SoftwareDistribution" on this computer looks like it is part of Windows update like @johnb6767 said.  I wouldn't mess with it.

you can delete temp files and folders (also in internet), and remove old, or not used programs

another -easy -solution is installing a bigger disk size (cheap now)
