The optional -type test restricts matching to files of the given type:

Like -find but operating on local filesystem and not on the ISO image.
This is subject to the settings of -follow.
.br
Find accepts the same -type arguments as -find. Additionally it recognizes
type "mountpoint" (or "m"). It matches subdirectories which reside on a
different device than their parent. It never matches the disk_path
given as start address for -findx.
.br
-findx accepts the -exec actions as does -find. But except the following few
actions it will allways perform action "echo".
