Dragging a file to the root Assets directory of a project causes large allocations and a long hang which can lead to a OOM crash
Steps to reproduce:
1. Open the attached user's project "EmptyDirectoryProject.zip"
2. Locate "NewUnlitShader" under "Assets/prefabs/effects/bloodNew/shaders/NewUnlitShader.shader"
3. Drag the file to the Assets project root directory in the Project Windows
4. Observe the hang that will either persist or lead to a OOM crash
Expected results: The file instantly moves, no/limited allocation overhead
Actual results: Large allocations and long hangs occur or OOM crash occurs
Reproducible in: 2021.3.28f1, 2022.3.6f1, 2023.1.5f1, 2023.2.0b2, 2023.3.0a1
Environment tested on: Windows 10
Notes:
-Customer suspects it's due to DragAndDropForwarding::AddItemsFromTargetPath iterating over every file in the project when a file is dropped in the root directory

Resolution Note (fix version 2023.3.0a3):
Improved DragAndDropForwarding to use significantly less memory and to be faster, particularly on very big projects. The file move now occurs close to instantly on the provided project.
