 +As of Tumbler 4.17.0 (first stable release 4.18.0), these settings extend to [[#customized_thumbnailers|external thumbnailers]] of the desktop-thumbnailer plugin, by adding the group "X-Tumbler Settings" to the ''.thumbnailer'' files. Further instructions and an example are given at the end of the ''tumbler.rc'' file.

This functionality supports custom ''.thumbnailer'' files placed in the ''XDG_DATA_DIRS/thumbnailers'' directories and the ''XDG_DATA_HOME/thumbnailers'' directory (which defaults to ''~/.local/share/thumbnailers''). The former is the place for system wide thumbnailers (normally in ''/usr/share/thumbnailers''), while the latter is the preferred place for the user's customized thumbnailers (see below).
