How to combine multiple RTF files into a single file using CF

I need to join multiple RTF files into a single RTF to accomodate a need for batch printing, ect.   I have tried all sorts of things to make this happen and what I keep ending up with is a combined RTF that has only the first file in it.  I have tried things like:

Writing a new blank rtf (combined.rtf)
Reading the first file
Appending the first file to the combined.rtf
Reading the second file
Appending the second file to the combined.rtf ...

When I do this, I only get the first file read or appended

I also tried things around ----

Read the first file into a variable
Read the second file into another variable

<cfset combined = '#firstFile#' & '#SecondFile#'>
Write the combined.rtf with the variable #combined#

I get the same thing.  Which ever file is in the combined string's  first postion is what I see in the resulting rtf

I also tried appending a "/page " to the first file hoping that this would provide a page break.  

It appears to me that the combined rtf is reaching an 'end of file' flag before getting to the second file.  Also, I'm not sure how all the leading formatting stuff might play into this.  

There must be a simple answer to this but I don't see it so, any help is appreciated.

you could use cfexecute and execute the command line
copy file1.txt+file2.txt destinationName.txt

It will combine the two files for you, lots quicker than reading it into memory with CF...

I em guessing that there is a end-of-file character that is getting appended - so that even though both files are there it is stopping writing after it encounters the first end-of-file character.

If you do this do you get both files :

<cfoutput>
#file1#
<br>---<br>
#file2#
</cfoutput>

If I do it that way, it doesn't get recognized as an rtf.  I just all the text in the two files dumped to the screen.  I think you are right about the end of file problem.  I just don't know how to handle it.  Can you somehow strip off the end of file marker and insert a page break?

Yes, I get both pages worth of output dumped to the screen.  I tried it a couple of different ways;

First,
<cfoutput>
#FirstRTF#
<br>---<br>
#SecondRTF#
</cfoutput>

Then I tried assigning it to  a variable

<cfset theCombinedFile = '#FirstRTF#' & '<br>---<br>' & 'SecondRTF'>

I can dump the contents to the screen or try to write it to a file with the same results as above.

What if you strip off the last character or try this

cfset theCombinedFile = Left(FirstRTF, (Len(FirstRTF)) & '<br>---<br>' & Left(SecondRTF, (Len(SecondRTF))>

It's not really a single character that indicates the end of the file it's a string.  If you manually ceate a two page file you can see where the second page is added to the first page and there is a long string of info connecting the two pages.  So, it appears that combing the two programatically is going to be more than just adding a br at the end of the file.  I have found a utility to do this called ConvertDoc but it's big bucks but at least I know that it is programatically possible.

I ended up just throwing in the towel and converting the documents to PDF's before I convert them to rtf's.  Yeah, I know it's not pretty but PDF let you manipulate the paging pretty easily.  It still runs more than acceptably fast so that's what we're running with.

Thanks to all for you input.
