Emacs Wanderlust filter folder

Question

I am new to Wanderlust so I've started configuring my wanderlust, but there's one thing I don't really understand, and that's how to add filters. The documentation tells me that the syntax is the following: ‘/’ condition ‘/’ target-folder I have no problem understanding the syntax, I just don't now where to write these filter, in which file, I've tried ~/.folder but that doesn't seem to work, it simply creates a folder in wanderlust called ‘/’ condition ‘/’ target-folder.

Thank you.

Answer 1

A filter folder doesn't copy or move messages — it is just a view into an existing folder, and modifying a message in a filter folder (e.g. marking it as read) will modify the same message in the target folder.

In order to transfer messages from a source folder into a different folder when performing a search, you need to combine a filter folder with a pipe folder. For example, the following will transfer matching messages from the +inbox folder into the +from-root folder whenever it is selected:

|/from:root/+inbox/|+from-root

Answer 2

I'm so sorry. I misread it, ‘/’ condition ‘/’ target-folder , I understood target-folder as a destination folder. Once again I'm so sorry for my stupid question.

So everything is working. But I'm under the impression that when the condition is met it doesn't move said email but copies it and so it is still present in the target-folder.
