How to restore files?

After saving my project multiple times, I closed it.
When i opened it up again it said there were files that could be restored.
I ignored this since i had already saved it beforehand and that should work.
However, this is not the case.
How do i bring up the menu to restore files?

in your project folders there is a saved folder…where many version of your saved files should be…
you could rename these files and put them into you content folder but make a backup of the project first.
