[anh5kor]

I have a requirement,where I have a text file which contain the path of all the .c file which are used in a project.I have to create a GUI which on button click read the file or the .c path and open the location,copy the respective .c file in another folder. Just like a script which copy the .c file from source to destination by reading the path from .txt file.

creating a button and reading a file I don't have any problem.But how can I achieve the opening of source location and copying of file from source to destination.
Please let me know some example or hint.
