Maybe there is a good explaination for this. I decided to make some room by burning stuff onto cds.
I have 2 versions of Office xp.
1/ folder containing virgin officexp about 448mb
2/ folder containing slipstreamed officexp about 621mb
I zipped both copies up with winrar (separately)and the result were
1/ virgin xp 400mb
2/ slipstreamed 356mb........nearly half of its former self
So then I tried with winzip and the results were the same
Can anyone give me any pointers or is there an explaination for this ......cheers
