I am using Windows 7 Ultimate operating system and the space of my hard disk is 320 GB. I want to know that how to decrease space in Recycle Bin to increase storage space. Can this be done using any of the techniques. I want to know this because whenever I delete any file, the recycle bin shows just one file, but the the used space in the C Drive increases a lot. Please reply soon and thank you in advance for any help.
