This manual page is only a short reference for Ex Falso. Complete documentation is available at https://quodlibet.readthedocs.io/en/latest/guide/.


Ex Falso may be given a directory to open on the command line.


Many places in Ex Falso allow you to use “tied tags”. Tied tags are two tag names joined together with a “~” like “title~version” or “album~part”. Tied tags result in “nice” displays even when one of the tags is missing; for example, “title~version” will result in Title - Version when a version tag is present, but only Title when one isn’t. You can tie any number of tags together.


Ex Falso allows you to rename files based on their tags. In some cases you may wish to alter the filename depending on whether some tags are present or missing, in addition to their values. A common pattern might be

<tracknumber>. <title~version>

You can use a ‘|’ to only text when a tag is present:

<tracknumber|<tracknumber>. ><title~version>

You can also specify literal text to use if the tag is missing by adding another ‘|’:

<album|<album>|No Album> - <title>
