Ok So I have a Support post going on @ Reddit located below.  But these batch files can do a lot of time saving  operations for those old playlists that no longer work due to outdated naming schemes.  One day i was searching the web to find some Best of lists to know which games i wanted to put on my handheld gaming device.   I woudl find one here and one there but all of them seemed to have files that did not match up with my newly acquired no-intro sets ran through RomVault.  So I fixed a couple and then I found some more.  This continued on until I found 2 large sets.  I knew i had to make updating these sets easier. For the next WEEK AND A HALF, I worked with Ai (What a chore) to create these batch files.  These files will extract the filename with extension and compare it to the source directory files.  It will then attempt to  Search for XML Filename (*.* against the directory files.  If it is found that becomes a match.  After that comes the reverse search, Directory filename (*.*, again if found these become Fuzzy.  It is suggested in this case you manually double check these matches. Which ever files that are not matched also goes into the csv file and labeled either XML_Only or DIR_Only.  The object is to match up the XML files with some of the remaining DIR files.  You simply cut and paste them on the line that matches up.  No need to delete any other info or extra filenames.  After that the 2th batch file will then take the csv file and repair the playlist xml file with the new correct filenames.  After that is complete the Optional 3rd and 4th batch files are capable of pulling the filenames from the XML and putting them without extensions in to a TXT file.  The 4th batch file then takes that TXT file and compares it to the Directory listings and will copy those files to a new directory along with another txt file of all missing files.  Once you locate your missing files from dumping your arcade board, you can rerun the 4th batch file and it will read the missing file and only copy those files over.  Once no missing files are lremainign the batch file will automatically delete the missing roms text file.  

IT IS NOT THIS COMPLICATED! 
 

This is an updated NoNag. Mad9k is no longer doing them.
Here is a temp fix for future versions as I only update once a year.
Mame dev has come up with a compromise to where you can put this line in your ini file and then the nags will not show up for a certain amount of time.  
Place this in ui.ini under UI MISC Options:
