Its the %temp% folder im referring to. It is not the problem whats in there(about 15mbs) but whats lands there durring the action that I take and thats over 16 gigs. And while I cannot make more than 7,5gb free on my system partition, the temp folder must be located on the other one which has plenty of free space.
So just moving the content of %temp% to ex. D:/temp/ will solve the problem durring the next run of the operation? I would never think its a way, is it? Back in XP it was like: right click My Computer –> Properties –> Advanced –> Environment Variables –> select temp variable and then click edit...
