How to move the files from the d: to the c: drive

To answer your question; you cut the files from d: to c: But I don't believe you are asking the right question Don't you mean how can I add the space on d: to c: making c: larger so it will hold more files? Answer is google Partition Magic, read about it throughly and then purchase the product.

that is what I mean, I have 177gb on d: and 7 gb on my c: I tried to defrag my system, I only have 2% and it takes 15% to defrag, this is when I found it out.

run disk cleanup before defrag. You will need to eliminate files to get to 15% or even Partition Magic won't work. HIGHLY recommend you backup all of your data before attempting to repartition using PM.

I have done disk cleanup many times. and still receive the same message. not enough space on my c: drive. is there something like partition, i am not computer knowlegable
