hi @FNBRVALOU
You have got corruption in a directory
In Windows
Type Windows key + R
In the box type “cmd”
Click ok, the windows batch console opens

cd %USERPROFILE%\AppData\Local\FortniteGame
del/s/q *.*

You are emptying corrupted copies of Fortnite code stored in you PC User path which is normally hidden from view

Probably best to run verify afterwards.

Verify after file problems

Hi all,

I would strongly advise against using the command line to delete anything unless you are an ‘Elite Programmer’ (aka L33T Programmer :mage:)

Also, the .pak file which is corrupt is not in your \AppData\ folder.

I’ve seen problems like this resolved in the past by deleting the C:\Program Files\Epic Games\Fortnite\FortniteGame\Content\Paks folder and then re-verifying the game files through the launcher. (Deleted files will then be re-downloaded)
