Hi btcman and welcome to bytes.com!

So, just to make sure I understand you correctly, if your PDF was called something like "instructions.p df" you want to rename it to "my.instruction s.pdf.stuff"? Or "my.instruction s.stuff.pdf"?

In any case, if you use Java you'll need File (especially File#renameTo(F ile)) and probably stuff like String#indexOf( String), String.substrin g(int, int) and/or String#replace( CharSequence, CharSequence).
