Confused by Folder Structure

[imacken]

In my DCS/Mods/Aircraft folder, I have 2 F-5E related folders, i.e. 'F-5E' and 'F-5E 2024'.  Yet, in Saved Games, etc. there is still just the one - F-5E.

Is it safe to delete the F-5E folder in Mods/Aircraft?  As things stand, I get 2 x missions showing in DCS.
