If your talking about your account page, you can just make a new folder, then click and drag models into the folder!

Let me try

1. Select the model you want to move, or Ctrl/⌘ and select all models you want to move to the same directory.
2. Click the scissors 'Cut' icon on the left-hand side of the screen.
3. Double click the directory you want to move the models into, to open the folder.
4. Click the 'Paste' icon on the left-hand side of the screen.

Or what Bishop said.

What about on mobile

Wait, there's a mecabricks app?
If your talking about the internet browser, i would assume the same thing but touch and drag!

No, I can’t, I’ll try on the comp

Yeah, I wouldn't use Mecabricks on mobile. It's just way easier to use a mouse and a larger screen.

Yeah!
