I have just been having a poke about, having a clean up, etc, and I noticed that my used disc space has suddenly increased by about 25%, for no apparent reason. This amounts to around 10-12Gb, which I can't account for. I have not installed anything new in the last couple of weeks, but when I checked last time, my free space was about 51%, now it is down to 27%.
Is there a way to check which are the largest files and folders on my C drive? I've emptied all my Temp files, and it only reclaimed about 100Mb.
