Going through and "cleaning out" the computer. Ran into old PSE 6, 8, and 9. Looking at the Presets in each and ran into some brushes, etc. that are not part of PSE 18. Can these old files be dragged into the respective preset files and work in 2018? Thought I would check here before starting this process in case there are some problems with doing this - and I don't want to reinstall 2018 again. Thanks for any insights. ~bruce.
