Merging folder of files according to name and contents.

I have absolutely no idea how to do this and everything I have done doesn't even come close.

Here's the scenario:

There are a number of files in a folder named in this manner:

agd.txt
stv.txt
frk.txt
dqp.txt

There is also a series of other files in the same folder with like file names but with a .doc extension. The catch here is that most but not all .txt files have a corresponding .doc file.

agd.doc
stv.doc
dqp.doc

What has to happen here is that each .doc file has to be scanned for specific lines that contain a word. Let's use "rabbit" as an example. It may be in the form of rabbit, rabbits, _rabbit, xxxrabittxyz, RABBIT, Rabbit, etc.

If any lines in agd.doc contain rabbit, in any form, those specific lines need to be appended to the bottom of the agd.txt.

This has to happen for each matching .doc and .txt file.

If there is a frk.txt but no frk.doc or a frk.doc but no frk.txt then nothing is to be processed for that particular file name.

Once a .doc file has been tested and the corresponding .txt file has been appended the .doc file needs to be deleted, even if rabbit was not found in the .doc. At the end of the routine the only .doc files that should be left are those that did not have a matching .txt file to append to.
