Permanent files using <Files> in Wix v5

[AntonyNifosi]

I am using Wix V5 to create a MSI installer.
I use the <Files> to harvest files, and I would like to have them permanent, meaning it's not removed at uninstall.
I only see the possibility to do it on a <Component> but can't use Files in a Component.
So how I could achieve this ?

I would like to do something like this :

 <Files Include="A/B/**" Permanent="yes" />

I already check the documentation but didn't notice any argument I could use to set the files harvested as permanent one.

I don't think this is a supported use case for Files. Are you using a bootstrapper? You could put all these files in a micropackage and make the entire package permanent.
