@Slxxm No, it's not. I've modified your screenshot to show you what I mean. The address bar, showing the full file location, is in red:
You can clearly see that the folder you're using is on the Desktop.
Please click Documents in the left sidebar, then open the Electronic Arts folder inside and go from there.
how about now
@Slxxm The same principle applies to your Tray files: if they're in a folder that's on the desktop, as your custom content originally was, you need to move the files to Documents > Electronic Arts > The Sims 4 > Tray.
If you put the files in that Tray folder and they still don't show up, please post a screenshot of the Tray folder as you did with the Mods folder.
