Map files disappeared

Today, several levels’ files have disappeared from my project. Those files were created during the previous 3-4 days and saved properly. Unfortunately, after opening the project, files are nowhere to be found. They somehow disappeared from the disk, and are not available neither in UE’s drawer, nor in file explorer.

  1. Has anyone faced a similar problem? Is there any way to avoid it in the future?
  2. As a software dev, I’m using git. Unfortunately, I couldn’t figure out yet how to use git with UE projects: diffs are big and not very useful. Are there any best practices on version control for UE?

Thank you.

  1. Yes. It could be possible that your maps are in your Saved/Autosaved folder. You can copy them into your levels folder and after launching your project double-click them. This will create a new level out of this aautosaved data and you can (hopefully) use them again.

Thank you for your reply.
Some of the lost maps were inside of Autosaved folder! :tada:

To my understanding, map consists of two files: .umap and .uasset (BuildData). In Autosaved folder, there is only .umap file. So, it gives “fail to load assets error”. Still, much better than nothing :relieved:
