If you are having some problems when it comes to Fortnite, one of the most common fixes would be to verify your files. When you verify your files, you essentially tell the client to scan your install directory and fix and broken files, or install any that are missing.
This will mostly fix errors when it comes to Fortnite not launching, opening or crashing on startup. Whilst it will also help most other problems you are facing in-game. It’s a much faster process than uninstalling and re-installing Fortnite all together.
Below, we have our guide on how to verify your Fortnite files. It works for both the Battle Royale mode (PVP) and Save The World (PVE). Meanwhile, we have some more guides available for Fortnite here.
This guide will only work for PC. If you are having problems on PS4 or Xbox One, try contacting Epic Games support.
Verifying your Fortnite files
To start, open up your Epic Games Launcher on PC. It will look like the image below. Just to the right of the launch button is a cog icon which opens some game settings. Click this cog icon to open a new menu.
From the list, choose ‘Verify’. It will start straight away and begin scanning your installation and ensuring there are no errors and it’s all up to date.
The entire process shouldn’t take too long, 10 minutes or so depending on the speed of your computer. You won’t be able to launch Fortnite during this time. However, once it’s finished verifying your files, Fortnite should launch successfully.
