What I need is a biggish cache for downloaded data --- hundreds of megabytes, and so won't fit on internal storage. It's not intended to be user-accessible. I note that Android puts a /android directory on SD cards containing the MediaStore database; it would be nice if there was an API for finding this directory and letting applications put stuff there... Of course, I still need a way of finding out how much free disk space there is first, to make this all work properly. It appears Java can't do this! There's an 11-year old bug on Sun's website asking for this ability. Apparently it'll be in Java 6... -- ┌─── ｄｇ＠ｃｏｗｌａｒｋ．ｃｏｍ ───── http://www.cowlark.com ───── │ "I have always wished for my computer to be as easy to use as my │ telephone; my wish has come true because I can no longer figure out │ how to use my telephone." --- Bjarne Stroustrup
