I want to reduce the size of a folder.  I have it sized to 75g and had it full at one point.  I have deleted data so now it has 45g in the folder.  It still is taking up the full 75g on my hard drive.  There is not enough space on my HD to copy all to a folder that is not encrypted  and then copy back to a new folder. I have re-sized folders to make them larger.  I have tried to re-size this folder to 50g.  Info tells me there is 45g in the folder but it will not allow the re-size.  Any help is greatly appreciated
