By those who install it.
It is with some apps anyway.
There are definitely good and bad programmed applications out there. So it
may be the case indeed that someone programmed an uninstall to somehow
expect everything is installed on the C: drive. Worst case, some
programmer hard-coded their idea of a file location instead of using the
user-designated location, so that some files do not get removed correctly.
But this is just bad programming.
I make a compromise myself. I put Windows on the C: partition. Then I
install all applications also there, which I feel 1) are more or less
permanent applications that I would not ever think of removing and 2) are
small enough that they would not overly bloat the C: partition. I put all
other applications on another partition. I put things like games always on
a separate partition, because games take a lot of space, and are not
permanent.
I think actually that every design more or less works, its just a matter
of personal taste. For me, I want the freedom to be able to repartition
everything on my hardisk without needing to re-install my OS, and this
means a relatively small C: partition (like, 20GB out of 80 to 250 total)
and then the rest either as one chunk or several.
