I have question, where SCS put file added to Package Repository(probably somewhere on FWDIR)

I have R75 installed on Windows, and i have still issue with low free space on C: (i select other partition when i installed SCS but only part of software was installed on second partition, FWDIR is located still on C: (FWDIR=C:\Windows\FW1\R75\fw1)

because i can't move this to other partition im thinking about setup new patch only for Package repository file. i need uploaded many files to package repository and will be great if i can keep this file in other partition.

is there any way to setup this ?
