I contain two folders which has several files. I would approximate to compare mutually folders and distinguish which folder has additional files and what are their names? How do I perform that in Windows 7 professional 64bit? Is there some helpfulness that I am able to download? Please help me to solve this problem. I am out of ideas now. I try to find about this on internet but after wasting 4 hours I am not getting any solution. Please help me. Thank you.
