Where does the package file go when you save..?

It goes onto your desk top or into a folder just type the name of the package in the search and it should show it .

I was replying to her question

Hi kenzielovesfoxes, before beginning your project, you should create a project folder. This folder can be created anywhere on your computer except in the Sims 4 game files or Sims 4 Studio files folders. Often, people will create this folder on their desktop. The folder can be named anything you want. Once you have done that, open Studio and clone the item you want to work with. When you click the Next button, the "Save As" popup box will appear. This is a navigation box that will allow you to navigate to the project folder you created. Once you have navigated to the folder, save the package in that folder. When you're done working on it and save the file, you will find it in the project folder.

To find something you have already created and saved, you can open it using the My Projects feature on Studio's front page. Under the My Projects button, you should see the last few projects you created. Click on the one you want to find. When Studio opens it, look in the top bar. The path to the file will show there, letting you know where you saved it.

i cant find my package file and i saved it and it won't let me pick where too put it where did it go?

When you have a .package open it tells you at the top where it is located.

Have you exported the textures? Photoshop can't open .package files, you need to export the textures to .png or .dds and then open those with photoshop.
