I have a Dell Inspiron E1705 running WinXP. For the past few months I've been getting a "low disk space" error on it, and Win Explorer tells me I have only 9Mb left free. In total it has a small 80Gb HD. The problem is that I've been steadily moving files and apps to a new laptop, which has easily cleared 10Gb or more of space on the C: drive. Yet after a week of not installing any new apps or files on the Inspiron, I get the same low disk space message. I cannot figure out what is eating up all of the HD space. I figure it must be a virus of some sort, but Norton shows nothing in scan results. Is there a file mgt utility tool that can show me which directory has been most recently updated, and which directory is the largest? Win Explorer is too clunky for this task.
