JMJ, Attached is an RAR of the files you need for the new Eduardo TSVComparer, Version 1.1.57.04. This is the same sort of arrangement you are familiar with already. There are 3 files: TSVComparer.exe the executable WPFToolkit.dll the library file which must be in the same directory as TSVComparer TSVComparer.exe.config the config file you must modify for your specific system paths In the .config file, there are 3 lines (and only 3 lines) to modify. Even a minor 1 character change on any other line will cause the program to crash. [I learned the hard way] Follow my path naming examples (bash_results or bash_new or bash_old) to guide you. Eduardo's choice of descriptive words is not very clear. In the output file, "LIL Shadow Record" should be "OTA"; Eduardo needs to correct that. In the output screen, there are four panes (un-labeled): Across the top of the screen: Added Removed Renamed Across the full width bottom of the screen: Remapped To get an all-on-one-page dump, select "Dump HTML" at the top right of the screen. Then, in your 'bash_results' file ( which you defined in .config) open the HTML output file with your browser - Firefox or IE or Edge or whatever. If you want to paste that output into an Excel, which is what I do, it takes three steps: 1. highlight the browser display of the data (the HTML file) and 'copy' the data 2. 'paste' the data into Windows Notebook or Wordpad 3. 'copy' the data from Notebook and 'paste' into Excel The intermediate step (Notebook or Wordpad) discards some HTML display information we do not want or need in the Excel. Yes, you can copy from the HTML display and then paste into Excel, but the Excel will be more difficult to work with. You'll see....
