Hello Sir, I'm expert in small app development using microsoft c#. I'm having 5+years experience, 5 star ratings & 100% completion rate here I can even develop a small demo version of the same if you want...let me know what you think
KNOW_HOW
I'll use the robust c# language to perform this task, in the GUI you need to select the source folder and destination folder and click on start sync button and then the application will copy/replace all the files to destination folder from source folder with a progress bar. It will replace the files if the same file exist at the destination folder already and the source folder have an updated version of that file
