Hi and thanks in advance for any help
I am getting a message that my hard drive is full, when i click on properties for the C drive it confirms that i am using 29.5 GB of my 30 GB hard drive. BUT when i add up the sizes of all the files on the C drive (including hidden files), it only comes to 25 GB.
Any ideas on why I can't find that missing 5 GB?

Thanks.

You also need to look at how much space each file uses on the hard disk, not just the size of the file itself. Assuming you are using an NTFS file system, I believe your 29.5 GB drive uses 32 Kilobyte cluster sizes. Storage space for a given file is allocated in 32 KB increments. That means that a 2 KB file and a 20 KB file would each use up a 32 KB block of drive space. A 33 KB file would use up 64 KB.

EDIT: BTW, Welcome to TSG.

So thats why properties of files and folders have size and size on disk?
