# Project transfer, will re-importing all my models damage my project at all?

Recently I had to transfer my Unity game project to another computer and downloaded the same version of Unity I was using for my 3D project and checked that all the files and folders were in the same place and everything.

When I start up the game though my models have vanished and in the hierarchy it just says missing prefab instead of telling me what it was, like it used to if I'd move a model to another folder or something like that.

It shows all my files there and I was about to reimport them all but I got a warning that said:

"Rebuilding assets is only if your project has been corrupted due to an internal Unity bug. It can take several hours to complete, depending on the size of your project.

Please submit a bug report detailing the steps leading up to here."

I am sure that re-importing all my models will fix this but I want to ask if this will have any negative effects on my project or possibly damage anything?

This game is extremely important to me and I've been working on it for the past 3 years(being self taught which is why it's taken so long and I'm still learning)

Thank you guys in advanced! :D

On the old computer, go to Edit>Project Settings>Editor in Unity and set Version Control to Visible Meta Files. You should now see .meta files appear next to all the assets in your Assets folder. Copy those over and your project should work as normal.
