On most file systems, rename() fails only if \a oldName does not
exist, if \a newName and \a oldName are not on the same

exist, or if a file with the new name already exists.
However, there are also other reasons why rename() can
fail. For example, on at least one file system rename() fails if
\a newName points to an open file.
If \a oldName is a file (not a directory) that can't be renamed
right away, Qt will try to copy \a oldName to \a newName and remove
\a oldName.

The file is closed before it is renamed.
If the rename operation fails, Qt will attempt to copy this file's
contents to \a newName, and then remove this file, keeping only
\a newName. If that copy operation fails or this file can't be removed,
the destination file \a newName is removed to restore the old state.
