hmmm, dunno what your problem is, a swap file wich is 160-170megs isn't really that bad, i have one wich is 800megs permanently.
if you want to delete files you cannot delete in windows, you'll need to reboot in DOS
or, if you are running a windows os who cannot reboot in DOS normally, you'll need a boot disc, wich you prolly know how to make.
but, when you are in DOS, be careful about what you delete, or your comp may never boot normally again =]
also, for win98, a great tool to make it better is "winboost 98" where you can change mostly everything you want in windows. you can also tweak your comp with this program.
if you have any other questions, please pm them to me and i'll help you as good as i can.
