   === Removable roll files
   
   After some time, there might be lingering queue files that are no longer used. Identifying these files is non-trivial as there might be tailers that are still on older roll files.
   
  -For example, appenders may be on roll file 10 and tailer A on file 3 and tailer B on file 5. In this case, it is only safe to remove the rolls 0, 1 and 2. In particular, roll 4 must not be removed.

   The removal candidates can be identified by invoking the `FileUtil::removableRollFileCandidates` method as described hereunder:

  The method `FileUtil::hasQueueSuffix` can be used to determine if a file has a roll file suffix (i.e. ".cq4"):
