Oops! I missed Getagrip's method.
Getagrip - it does seem a bit fraught, but I guess if it works ...
Out of curiosity, how much RAM do you have?
What happens if you start fooling around with big files with a number of apps running. eg a photo editor a 60meg file, with Outlook, Excel and Word also running? I have 256Mb RAM and that scenario fires up the swap file.
