Delete all unused assets

I don’t know in which editor version this was added, but the “Show unused assets” option does exist in the Content Browser, under Filters > Other Filters > Not Used In Any Level. This applies to all Actors that are placed in the world and assets that are referenced through Blueprint by these Actors. For assets that are referenced in CPP, I’m not sure if they will be picked up by this filter.

Note, that if you change the contents in your scene, you need to save the scene, then disable and enable the filter again to reflect the changes in the Content Browser.

I am not sure if the other guys talking about what I am now, but in my case I need to get rid off the RESIDUE LEFTOVER DELETED UASSETS CREATED IN CONTENT FOLDER, which are not visible in the Content Browser anymore, like I have deleted some materials - yes, they were removed from the Content Browser BUT they are still there in the project Content folder/subfolders. Actually, I have no clue why is this “feature” there: I thought if I delete something from the Content browser it will be wiped out from the disk (Content folder) too.

So then I was scratching my head like for several hours WTF is going on here, when UE4 is telling me there already is material with the same name I am trying to assign to my new material, yet there definitely is not. Only to find out they stayed inside the Content folder/subfolders, so if one does not remove them manually one will not be able use the name of such object although it is not shown in the UE4 content browser…go, figure! :mad:

Using latest UE 4.25.3
