Well, I know nothing on win32 but try with "wb"

> newFile = File.new(CustomDir + newFilename + extension, "w")

&nbsp;&nbsp;&nbsp;newFile = File.new(CustomDir + newFilename + extension, "wb")

do say that you want a binary file (without conversion)

I am just guessing (I don’t use MSW), but you may try :

newFile = File.new(CustomDir + newFilename + extension, “wb”)

Note the “wb” open modifier (I would try “bw” also…)

Thanx, Guy  
That’s it. It’s works fine with “wb”.
