Can't Delete?
 

I am trying to delete a large file on my computer. The only problem is, it's on my windows 7 bootcamp drive, and it won't delete. After a little time skimming this forum, I found the problem seems to be that I don't have the administrative power to delete something on bootcamp. So, my question is, is there a way to give myself administrator capabilities on bootcamp? or is there a windows program that is like Omni disk sweeper that I could install and use on windows directly? Thanks in advance, I have been trying to do this all morning, to no avail.
