”I do not actually have directories labeled 'Defrag' and 'Uninstall' but I did not want to name the programs I am actually excluding on my smaller drive. As you can see though, we are able to just list what we want excluded one after another. The 'wlx' files were something you are unlikely to see again as the program that used them is no longer supported. Because there are no spaces in the names we do not need the quotation marks, but I use them out of habit. At this point, you should be able to go through and generate the batch file(s) you will want to use. To test the batch file(s) I suggest inserting the USB drive you want to update, making sure the destination uses its drive letter, and run the batch file with the command prompt. This way you will be able to watch as the instructions are carried out, and see if any error occurs. Also, be sure you are using 'dummy' files and folders; if you accidentally setup the instructions to delete files, you will not lose anything important.”
