If the answer to your question is as simple as textFile=File.open("~/foo.text","w") binaryFile=File.open("~/bar.dump","wb") Then everyone will tell you to read up ;), but since it's probably more complex, tell us what the issue is. (and if it's writing Marshal.dump stuff, your problem isn't writing, it's reading) --Kyle
