This is a program that allows you to select 2 folders and merge them. Merging is done by comparing the folder structure inside both folders and copying both files and folders from both folders to the merge folder. If there is a conflict the program will decide based on the selected file property: Last edit date, Creation date, size or last access date. Download it here.
I made this using Visual Studio 2010. I used the visual c# .NET framework, wich is my favorite development envirement atm.The programs icon was made using autocad, illustrator and photoshop.
