EZPatch - Fortnite Replay Patcher

EZPatch is a lightweight userfriendly desktop app made to fix broken Fortnite replay files after game updates.

When Fortnite releases a new update old replays become unplayable because the version information no longer matches the current client. EZPatch solves this by copying the correct version bytes from a working (new) replay file and patching them into one or more broken (old) replay files.

Features

• Single File Mode: Patch one broken replay using one working replay.
• Batch Folder Mode: Patch all replay files in a selected folder using one working replay.
• Auto Mode: Automatically detect the latest replay in the default Fortnite folder and patch the entire folder in one click.
• Safety First: Keeps original files by default, moves them to a Backups folder in your fortnite folder, this can be disabled. (not recommended)
• Modern UI: Built with CustomTkinter with help from Gemini 3.1.
