Is financial or any other information downloaded to a portable
external hard drive connected through a USB drive retained on the
internal drive as well?

Hi alan27-ga,

If you download a file directly to a portable USB drive (an external
hard drive or flash memory device), that file is not also stored on
the internal drive unless you take specific steps to do so (such as
copying the file from the USB drive onto the internal drive).

Having said that, there are situations where part or all of the
contents may be copied to the internal drive during the normal
operation of software applications. For example, if you have viewed a
document from the USB drive on your web browser a copy of that
document may be held in the browser cache (on the internal drive).
