Fz reports more files used than I can find...

First off - I'm a bit of a newbie at all thus HTML stuff. I've put up a simple webpage - nothing spectactlar - and use FZ to upload the pages & photos. I can use a web-based uploader provided by my ISP but it's rubbish. It's slow and can only upload one file at a time (load the IPS's webpage - browse to the file to be uploaded - hit upload - then reload webpage again for the next file.. and so on etc) so Fz is infintely better. Problem is that when I log in through Fz, even if I delete all the files from my webspace, Fz still reports that I've used 23% of my allocation, as did FTPX when I tried it. No files appear on the remote pane, and my IPS webpage also reports that I've used nothing... I've even used the rubbish IPS webpage to delete everything but still Fz reports this 23%... How can I find these files and how can I delete them ?
