How to erase all the files and folders in the Selected existing directory

[marcel]

Oh, yes, I see now.
That will not work because at that point the parent dir is possible not to be empty, therefore the call will fail.

Do it like I have shown you.

Another solution is:

void Form1::DeleteData(String dirViewPath) 
{
 ...
 //function body
 ...
 
 if(!dirPath.count()==2) //"." and ".." -- might not be  the case. if not,. test with 0 
 {
   dirPath.cdUp();
   dirPath.rmdir(dirViewPath);
 }
}

void Form1::DeleteData(String dirViewPath) 
{
 ...
 //function body
 ...
 
 if(!dirPath.count()==2) //"." and ".." -- might not be  the case. if not,. test with 0 
 {
   dirPath.cdUp();
   dirPath.rmdir(dirViewPath);
 }
}

To copy to clipboard, switch view to plain text mode 

This will work. I forgot to mention that you have to go one level above dirViewPath, in order to delete it.
