When using Unity to download assets in the Asset Store, or using Package Manager to download Package, or using Unity Hub to download Unity, they can only be downloaded/installed on the C drive, and Unity does not provide a way to customize the download/installation address, then if What should we do if our C drive is not enough? You can use the mklink command to create a folder for Unity's download/installation directory on the C drive and link it to other drives to save our C drive.

As shown in the figure above, a folder link named Hub (UnityHub will install the downloaded Unity into this directory by default) is created in the C:\Program Files\Unity directory, which actually points to the F:\Hub directory.

As shown in the figure, this folder Hub marked with an arrow is a folder link. It is not a real folder, but something similar to a shortcut.
