Ok, can you give me output with an explanation of what you want to do ?
My guess is that you are misinterpreting the output of free and make the 
wrong conclusions.

Many people coming from windows (I was one of them too many years ago) 
only had the used/free concept and considered everything that is used, as 
being 'not free'.

Reality is a bit more complicated and Linux makes use of _all_ memory, 
although much of it can be considered free using the Windows terminalogy.
