HI Paul,
Thanks for replaying ton this post.

Yes I tried this ( But this doesn't work for me) i tried also many other solutions from here and didn't manage.

Basically i have folder and then subfolders

(subfolder1) -doc1.docx,doc2.doc
(subfolder2) -doc1.docx,doc2.doc
(subfolder3) -doc1.docx,doc2.doc

Result:
(subfolder1) -doc1.docx,doc2.doc,combined.docx
(subfolder2) -doc1.docx,doc2.doc,combined.docx
(subfolder3) -doc1.docx,doc2.doc,combined.docx

so need to save in the same folder where is this 2 documents.
