When copying a folder located on the desktop, there should be copy options
With this option, we should be able to copy only the types of files we want among the files under this folder.
For example, we should only be able to copy files with .xls extension under that folder.
and the directory of these files must be preserved
that is, the system will only copy the xls files under the folder.
As a result, the new duplicate folder should contain only xls files in the same subdirectories. Other file types should not be copied.
