Temp files accumulate although I sometimes remember to delete - but if I click delete they ALL go, including passwords, etc(like my login details for this site)and there are some I want to keep. Is there a simple way to select the handful that I really want while deleting the rest? OS is Vista, but I don't think the issue was greatly different in XP.
for passwords and logins you could use roboforms - the free version allows you to have 30 different logins etc. If you want more you have to pay for the registered version. It cost me about £10 if I remember.
