I am running out of storage on my laptop and i need to move all my unity project but I don’t know how. And if it helps I am a MacBook user.
step 1 (always do this): Make sure the project has version conrol, like gitHub
Step 2: If you dont use the project anytime soon, and the project is backed up on github, just delete the project
If you do actively work on the project, maybe use a very fast external SSD and move the files there. if something goes wrong, you have the git backup. External SSDs are often slower than native file access, so for the most important projects try to keep them on the native SSD
^ ^ ^ This, but realize that backing up OR source-controlling the project WILL take extra space.
In 2026 you want to focus primarily on saving your work correctly, so get a cheap thumb drive and copy everything over FIRST, just in case, before you possibly cause issues by running out of space again.
PROPERLY CONFIGURING AND USING ENTERPRISE SOURCE CONTROL
I’m sorry you’ve had this issue. Please consider using proper industrial-grade enterprise-qualified source control in order to guard and protect your hard-earned work.
Personally I use git (completely outside of Unity) because it is free and there are tons of tutorials out there to help you set it up as well as free places to host your repo (BitBucket, Github, Gitlab, etc.).
You can also push git repositories to other drives: thumb drives, USB drives, network drives, etc., effectively putting a complete copy of the repository there.
As far as configuring Unity to play nice with git, keep this in mind:
I usually make a separate repository for each game, but I have some repositories with a bunch of smaller test games.
Here is how I use git in one of my games, Jetpack Kurt:
Using fine-grained source control as you work to refine your engineering:
Share/Sharing source code between projects:
Setting up an appropriate .gitignore file for Unity3D:
Generally the ONLY folders you should ever source control are:
Assets/
ProjectSettings/
Packages/
NEVER source control Library/ or Temp/ or Logs/
NEVER source control anything from Visual Studio (.vs, .csproj, none of that noise)
Setting git up with Unity (includes above .gitignore concepts):

It is only simple economics that you must expend as much effort into backing it up as you feel the work is worth in the first place. Digital storage is so unbelievably cheap today that you can buy gigabytes of flash drive storage for about the price of a cup of coffee. It’s simply ridiculous not to back up.
If you plan on joining the software industry, you will be required and expected to know how to use source control.
Source control does require learning, but there are TONS of tutorials and courses and online reference.
You should strive to use source control as confidently as you use your file/folder system.
“Use source control or you will be really sad sooner or later.” - StarManta on the Unity3D forum boards
In short:
- close the Unity editor if open
- delete the /Library and /Obj folders from the project’s root (>80% of the folder’s size!)
- drag & drop the folder to its new destination
- in Unity Hub, use the Add button to add the project at the new location
Worth considering: internal storage is almost always the fastest. Running a Unity project on a USB drive or stick can severely degrade editor performance.
Also: Storing a Unity project in a cloud-synched folder (ie iCloud) is a recipe for disaster (project corruption), and a terrible waste of cloud space on top (90% of it is temporary data).
