File modification time: this method ignores the file-names and deletes
the files which were modified least recently.
Maximum used space (MiB): Specifies a threshold, in terms of storage space,
that will trigger deletion in the directory. If the total size of the files in the
directory is greater than the value specified here (in mebibytes), files are
removed in the selected sort order until the threshold is no longer exceeded.
Maximum number of files: Specifies a threshold, in terms of number of files,
that will trigger deletion in the directory. If the directory holds a larger
number, excess files are deleted in the selected order until the specified
number remain.
Note: At least one of Maximum used space (MiB) and Maximum
number of files must be specified. If both are specified, they will
both be respected.
Note: Each directory cleaner instance checks its configured
directory once per hour so, if an application generates files rapidly,
the total size or number of files in the directory may grow to
considerably more than the configured threshold values.
