/********************************************************************************
Clearfiles (): Empties only files within the folder (excluding files within subfolders)

void Clearfiles (const QString &folderfullpath)
{
Qdir dir (Folderfullpath);
Dir.setfilter (Qdir::files);
int filecount = Dir.count ();
for (int i = 0; i < FileCount; i++)
Dir.remove (Dir[i]);
}
