The Package Manager can load a package from anywhere on your computer even if you saved it outside your Unity Project folder (for example, if you have a package called and you save it on the Desktop but your Unity Project is under the Documents folder).

You can also use a folder inside your Project folder, provided that it is not one of the reserved Project sub-folders.

Local packages inside your Project

You can place a local package anywhere inside your Project except under these folders:

项目文件夹: 原因:
Assets If you place a package inside this folder, the Asset Database imports any Assets under this folder twice: once as Assets and once as Package contents.
Library 请勿修改此文件夹的内容。
ProjectSettings This folder is for settings Assets only.
Packages If you place a package under this folder, the Package Manager automatically interprets it as an Embedded package, regardless of the reference in the Project manifest.
