Epic’s launcher only lets you move Fortnite by uninstalling and redownloading it. Here’s how to move Fortnite to another folder or copy it to another PC—without the 32 GB download.
Back Up Your Fortnite Folder
First, you’ll need to create a backup copy of your Fortnite folder. Fornite installs to C:Program FilesEpic GamesFortnite by default, so you’ll probably find it there. Navigate to that folder in an Explorer window.
Right-click the “Fortnite” folder and select “Copy” to copy it to your clipboard.
Paste a copy of the Fortnite folder into another location. For example, if you plan on moving Fortnite from your C: drive to your D: drive, you might want to paste it to your D: drive. If you plan on moving Fortnite from one PC to another, paste the Fortnite folder onto an external USB drive.
Do not immediately copy the Fortnite folder to your desired location. For example, if you want to install Fortnite to D:Epic GamesFortnite, don’t immediately copy the folder there. Instead, consider copying it to D:TemporaryFortnite for now.
Wait for the file-copying process to complete before continuing.
