increasing the driver size

Hi all...

I'm having some problems with the limited drivers size: "No space left on device"

[SOPC Builder]$ df -h

Filesystem Size Used Avail Use% Mounted on

C:\quartus\bin\cygwin\bin

30M 30M 0 100% /usr/bin

C:\quartus\bin\cygwin

30M 30M 0 100% /

c: 30M 30M 0 100% /cygdrive/c

d: 19G 66M 19G 1% /cygdrive/d

f: 14G 11G 3.7G 74% /cygdrive/f

z: 30M 30M 0 100% /cygdrive/z

I would like to know if someone knows how to increase this field... there are a lot of free space on disk.

Thanks all...

Maikon.
