How to delete favourites?

My wife has saved countless ( hundreds ) of items that she viewed on craigslist, in favourites. I can delete them, one at a time, but would take me hours to do so. Is there a way to do this quicker? In the last few weeks, her computer is running very slowly, especially in outlook and Edge. I can't see anything in taskmaster to cause this, except for memory use at 60% or higher. It is an Intel 2.2 GHz with 4 GB memory and SSD HD. The memory is maxed out. Thanks for any responses.

The first place I looked. They are not there. Favourites Bar and other Sub Folders are but not the multitudes I am looking for. In Edge they show up in the " Imported from IE Explorer" folder.

@ddgm91, the Edge Favourites are stored in...

Code:

%LocalAppData%\Packages\Microsoft.MicrosoftEdge_8wekyb3d8bbwe\AC\MicrosoftEdge\User\Default\Favorites

...copy the above and paste it into File Explorer's address box. You may need to close Edge and restart it for any deletions to take effect.

Thank You Bree, I'll try that. Sheesh! No wonder I couldn't find it. I used to consider myself some what computer savvy.
