Too much data ?

Hi

I just reinstalled win 7 64 bits & everything on my 120 gig ssd drive but this time It only remains 20 gigabytes instead 37g before the reinstallation … STRANGE !?

Is this is normal that in ''C:\Users\AppData\Roaming" there is 10.4 gigas of data in the Steinberg folder ?

Thanl you

what do installation requirements say?
