I am afraid, I did not describe my query clearly. I tried to describe it more
clearly, below:

I want to read a folder name on the disk (in order to extract all the files
under this folder and its subfolders). Presently, my application requires to
type the path, in a textbox, as below, for example:

"d:\documents\projects\reports\cities\"

I want a way to choose a folder, like the above , for example, by clicking
from the list of folders instead of typing the path (sometimes much longer
than the above example). Consequently, my applications extracts all the files
under this folder and its subfolders.

Please note that I need to read the FolderName only, not the FileName(s).

Regards,

Rabi
