Did you check that? That's most likely the reason for all your trouble. What I often do is to open the file "as binary" in the IDE and look. Do File->Open->File, use "Open With", then select "binary editor". If you see FF FE, FE FF, or EF BB BF at the beginning of the file, it's a Unicode file saved with a BOM (Byte Order Mark) at the beginning (Windows editors typically use BOM to mark Unicode files). You will also note that, if it's FF FE at the start, and text is mostly standard Latin letters, every other byte is 0. That's UTF-16 encoding you're seeing. If you opened it in write.exe, and just saved it, it's possible that it saved it "back" as RTF. Since RTF is not unicode, it's likely that two-bytes per-character (often the case with UTF-16 encooding) went back to one-byte-per character, hence half the size. Goran.

But in addition, a file that is written by Word has an AMAZING amount of RTF garbage in it, that will not be retained if you pass it through WordPad. So until you actually examine the file contents, there's no way to say which of these two explanations might be valid. joe **** > >- JY. > >"Goran" wrote: > >> On Apr 28, 4:43 pm, Goran <goran.pu...(a)gmail.com> wrote: >> > On Apr 28, 3:59 pm, JY <s...(a)nospamgroup.com> wrote: >> > >> > >> > >> > > "Joseph M.
