I have no idea how big your string is, but I can see how a large enough string might eat up memory. Perhaps you can have an overloaded CreateFileEncoding() method that takes a StringBuilder instead of a string. That way, you don't utilize .ToString() until you're in the process of actually writing it out to a file

loStreamWriter.Write(tcStringBuilder.ToString())

Would that work ok for you?

>>Is the exception occurring at loStringBuilder.ToString() or is it occuring somewhere in the CreateFileEncoding() method when the method attempts to do something with the string?
