2 folders named 'dm'

[hsfrey]

I'm a clueless newbie who just tried to download D from digitalmars.
I got 2 zips, dmc.zip & dmd.zip.
The first expanded to a folder named 'dm' & I moved it to my Programs folder.
The second expanded to 2 folders, one named 'dmd', and the other named AGAIN,
'dm', but much smaller than the original 'dm' folder.
I can't move it to my Programs folder, since it'll overwrite the 'dm' already
there.
Was Gibt?
