Where League of Legends saves replay (.rofl) files

The Replays folder

Every replay the League client downloads is saved as a .rofl file, named after the game: the server, then the game's number, for example EUW1-7987918401.rofl. They all go into one folder.

• Windows: Documents\League of Legends\Replays in your user folder, so usually C:\Users\you\Documents\League of Legends\Replays. If your Documents folder is synced with OneDrive, look under OneDrive\Documents\League of Legends\Replays.
• Mac: ~/Documents/League of Legends/Replays.

To be sure, open the client, go to Settings → Replays. The folder path is written there, and you can change it.

Saving a game, custom games included

The client does not keep every game on its own. Open your match history in your profile, find the game, and press the download button on it. Custom games show up in match history like any other game, so your in-house games can be saved the same way.

Do it soon after the game. Replays can only be downloaded for a while after a game, and the client only plays back replays from the current patch. The file itself keeps everything that was recorded, so a tool that reads the file can still use it after the patch changes.

What is inside a .rofl file

A replay holds two things:

• The end-of-game scoreboard for all ten players: kills, deaths, assists, damage by type, gold, CS, vision, items, runes, objectives and multikills.
• The recorded game: the stream of everything that happened, which is what the client plays back, and what a timeline of gold, kills and objectives can be read from.

Collecting a night from the whole group

Each player's client only saves the games that player downloaded. For a full night, ask one person to download every game, or collect files from several people. Zipping the Replays folder and sending it in your group's chat works fine.

In-House Lab takes the files one by one or as a zip, and counts a game only once however many people upload it.
