How can I download Fortnite to my USB stick (128GB)?

I have the following problem:

I wanted to transfer Fortnite to my USB stick because my MacBook only has 128GB. Could you maybe tell me how to get Fortnite on a 128GB USB stick? It keeps breaking off at EPIC Games.

Hard drive: 128 GB, 2017 generation

My USB stick has 128 GB.

I look forward to your answers and thanks in advance!

Make sure that the stick is formatted in either HFS + (Mac OS Extended), APFS or exFAT. With FAT32, files can be up to 2 GB in size, which may not be enough.

Otherwise you only have to select a directory on the stick as the installation path when installing in the Epic Games Launcher.
