Exporting Your Project

To back up your Unity files, you need to back up the entire contents of your Unity project folder, NOT just the .unity files.

There are a couple ways to do this, but The easiest way to do this is create a unity package:

export a package

Instructions
To Export the package…

  • In Unity, right click on the ‘Assets’ folder in the project tab
  • Choose “Export Package”
  • In the window that opens, verify that is shows a big list of all the files in your project, and hit Export
  • Give the file a sensible name, and save it.

To Import the package…

  • Create or open a project where you’ll import the package
    (Note: importing a package will overwrite any duplicate files, so be careful)
  • Go to Assets/Import Package and select your package file

 OR
Drag and drop the package file into the project tab

pros: simple, small filesize
cons: doesn’t include certain project settings in the transfer (not typically a problem)






2: Copy the entire Unity Project folder

Only do this if you have issues with method one

Instructions

  • (IMPORTANT) QUIT UNITY!
  • …
  • Really, did you quit unity?
  • (Optional, but highly recommended) temporarily move the ‘Library’ folder onto your desktop, or otherwise outside the project folder.
    The ‘Library’ is a very large folder that does not contain anything unique to your project, and is just a cache of files that can be regenerated.
  • Zip the folder.
  • Move the library back.

export a package

pros: Includes all project settings. Don’t need import step.
cons: Very easy to mess up.

PRO TIP: Zipped files transfer to/from USB drives significantly more quickly than raw project folders

NOTE: you can also delete the Library folder of your project to save space if you know you won’t be opening your project for a while.

3: Use Version Control (Like Git, or Unity’s built-in version control)

This is an advanced method. Either investigate on your own, or check with the instructor.
