      Description

      The behavior of QFile::rename is inconsistent when used on a file in USB flash drive and when used on a file in local HDD.

      Behavior on local hdd:

      • If a file with the new name exists, returns false and nothing will be done

      Behavior on usb flash drive:

      • If a file with the new name exists, returns true and overwrites the existing file without a warning

      Steps to reproduce:

      • Run the attached project
      • Select a test directory on usb flash drive
      • Select a test directory on local hdd
      • Click "Run test". (Creates 2 empty sample files on both target directories and attempts to overwrite one with the other using QFile::rename)
