deleted everything and startup disk is still full

[emmanevada]

I have a 2009 mb pro and several days ago I got a warning that my startup disk was almost full. I deleted hundreds of videos and pictures I no longer needed, freeing up about 43 gb after emptying trash. Now I am getting the same warning again and it is telling me i only have 900 mb left! How is this possible?! I haven't downloaded anything or used the computer heavily since then. I have deleted basically everything except the bare bones and it still isn't freeing anything up. Help??

You know you have to empty the trash, not just drag things in there, right?

Have you partitioned the drive? Any screen shots?
