Where do i have to store a Custom SmartArt Color (.gcsx) or a Custom SmartArt QuickStyle (.gqsx)

Hello

I created a Custom SmartArt Layout (.glox), Custom SmartArt Color (.gcsx) or a Custom SmartArt QuickStyle (.gqsx).

I copied them in the Folder: "%APPDATA%\Microsoft\Templates\SmartArt Graphics"

But when i open "Microsoft PowerPoint 2016" (Windows) i see only the Custom SmartArt Layout (.glox).

Is the directory "%APPDATA%\Microsoft\Templates\SmartArt Graphics" correct for the GCSX- and GQSX-File or do i have to store then in an other Directory?

Thanks for your attention.
