Hi Vero,
I've added the folders to my search scope (the individual folders) and it now works so thank you for your help! However, will I have to do this for every folder in the future? And Alfred and Spotlight was able to locate a folder inside of the folders I was initially trying to locate, so I'm kind of confused as to why it wasn't working. If I don't add each individual folder to the search scope, they don't pop up as a result, but what is contained in them will (only some though).
I've unable to attach a picture of my 'Default Results' but I have 'Preferences' and 'Contacts' checked, I recently checked 'Folders' and 'Documents' as I thought that would expand the search. I have also checked the 'macOS Applications folder' and 'Folders in Home'.
My mac is macOS Catalina and my Alfred is version 4.0.9. I am typing in 'open [file name], eg. open Economics. I scroll all the way down to the last result and the folder doesn't show up.
My issue now is that while I can open the folders I initially couldn't, I have to individually add them to the search scope. Even then, I can't open the files contained inside them using Alfred, aside from one folder which is empty. I didn't have this issue last week so I'm not really sure what happened between then and now.
Hope you're staying safe,
Martina
