I was just about to delete a few more folders when I thought that there's no way those could be empty. I opened them in Explorer and there are definitely files in there. So what can cause Everything to think that the size is 0?
Thanks for the clarification. I'll use those going forward.
Specifically for the issue I'm dealing with, these are folders with files that are not empty. If I right click the folder and select Properties, each show a number of files and a non zero size (as an example, one of the folders show 21 files and 10.5MB).
