Monkey Merge Xp   
by Softcns   

Automatically merge multiple Microsoft Word documents (DOC and RTF files) and all plain text files such as CSV or HTML files together into one big target file. Merge many Excel XLS workbooks and worksheets into a single worksheet. Combine Adobe Acrobat PDF files. You can filter files by file name, file size and file pattern. Files are displayed in the main window in alphabetical order, order of size, date modified order, date created order or by file attribute. All operations can optionally recurse subfolders.
