Mantaining longer than 256 chars path-filenames, can't read locked files, cant copy not owned files, can't read files due to bad sectors, replace older files in destination, etc.
I wish a checkbox to continue no matter what, and skip any problematic files or dialogs, which I could retry after a comparisson. In that way most of the huge copy would be done by next day. Now I'm overdue one day becuase of this issue and won't be able to deliver in promised time
