Reducing Project Sizes

Upon opening a project UE4 will generate various files and folders if they do not already exist:

  • .vs

  • Binaries

  • DerivedDataCache

  • Intermediate

  • Plugins/*/Intermediate (any Intermediate folder inside a plugin)

  • Saved ProjectName.sln (only if your project has a c++ code in it)

These files and folders can be deleted to reduce the total size of your project when archiving, sharing and/or moving the project. They are often times also excluded from source control using a .ignore list for example.

The Binaries folder inside of plugins should not be deleted as they might contain pre-built libraries of which the source code is not distributed with the plugin and therefore cannot be regenerated on demand.
