The easiest way would be to use a "replace" action.
If you need something else, have a look at the FAQs
There you find hints on how to use an action and a specific approach to remove space characters (trailing, leading, repeated):

> How to remove/trim leading and trailing spaces [Video tutorial for these actions](http://www.vimeo.com/7756545) Leading spaces: Action type: Replace with regular expressions Field: \_TAG Regular expression: ^\s+ Replace matches with: ^ matches the beginning of the string. Then \s+ searches for all whitespaces till a different char occurs. The whitespaces found will be replaced by nothing and, thus, deleted. Trailing spaces: Action type: Replace with regular expressions Field: \_TAG Regular expression: \s+$ Replace matcβ¦

This field variable describes the whole tag data. It spares you the effort to name every field explicitly. Yet, a word of warning, it may lead to undesirable results if you let loose a action on the whole tag data and you do not know exactly which data is in the tag.
A better approach would be to treat only the fields where you really suspect multiple successive space characters.

I think that the filename is included in the treatment if you use `_ALL`

@asamirid Please be aware that \_TAG also includes the Lyrics tag `UNSYNCEDLYRICS`. Every change you make will be executed for your embedded lyrics too. So again: Be very careful using \_TAG.
