Qt's understanding of file permissions is limited, which affects especially
the \l QFile::setPermissions() function. On Windows, Qt will set only the
legacy read-only flag, and that only when none of the Write* flags are
passed. Qt does not manipulate access control lists (ACLs), which makes this
function mostly useless for NTFS volumes. It may still be of use for USB
sticks that use VFAT file systems. POSIX ACLs are not manipulated, either.
