I downloaded project from github.
Project was intended for UE 5.5.0.
Project size was 1 Gb on disk.
Sources was included.
I recompile project for 5.5.3. (Everything is fine)
Recompiled project size became 70Gb.
Binaries folder - 44 Gb
Intermediate folder - 32 Gb.

I plan to work in version 5.5.3. And nothing else.

The question is:
What files/folders i can safely delete WITHOUT NECESSITY OF RECOMPILING project in future?

My situation:
I’m making backup from time to time (copy/paste project folder), so sometimes i want restore my backup. So my backups takes too much space. So, maybe some files appeared in project folder during recompiling not necessary for running build?

Hello there @9Evgeny9!

The short answer would be, if you want to avoid recompiling your project entirely from the backup, then yes, you will need to keep the contents of Binaries and Intermediate folders. Deleting them will enforce a compile the next time you try to open the project.

The elements that are not needed for run, or need to be recompiled, are mostly elements from folders Saved, DerivedDataCache, and StagedBuilds. You could also delete .vs and build, but these ones wil be re-created on first run.
