I have recently upgraded the system with windows 7 64 bit operating system. Previously I was using windows XP which was really working nicely. I have found some trouble in windows 7 that I have two folders which has various records. I would like on the way to contrast both folders and observe which file has more records and what are their names? How do I perform that in Windows 7 64bit I was able to do this in windows XP? Is there any service that I am able to download? Please help me.
