The basic process: read, extract, place in the folder

Installing a World of Warcraft addon means downloading a compressed file, extracting it to your computer, and moving the extracted folder into your WoW game directory. The game reads whatever folders are in that directory when it starts, so once the addon folder is there, the addon loads automatically. You do not need to run an installer or restart your computer — just restart the game.

Most addons come as a .zip or .rar file from a website like CurseForge or WowInterface. Your computer already knows how to extract .zip files (right-click, select "Extract All"). For .rar files, you will need a free program like 7-Zip or WinRAR to do the same thing. After extraction, you will see a folder with the addon's name inside.

The destination folder differs slightly by operating system and which version of WoW you play, but the principle is the same: find your WoW installation, open the Interface folder inside it, then open the AddOns folder inside that. Drag your extracted addon folder there, and you are done.

Key Takeaways

  • read addons only from established sites like CurseForge, WowInterface, or Wago.io, which scan for malware before hosting files.
  • Extract the .zip or .rar file to a temporary location on your computer, then move the resulting folder to World of Warcraft/Interface/AddOns.
  • Restart the WoW client completely after adding addon folders; the game reads the AddOns directory only at startup.
  • If an addon does not appear in your game after restart, check that the folder name matches the addon's internal name and that you placed it in the correct AddOns directory.
  • Keep addon folders organized by disabling or removing ones you no longer use, since too many addons can slow down the game's startup and performance.

Finding your WoW installation folder on Windows

On Windows, World of Warcraft is usually installed in C:\Program Files\World of Warcraft or C:\Program Files (x86)\World of Warcraft, depending on whether you have a 32-bit or 64-bit system. If you installed it elsewhere, open the Battle.net launcher, right-click on World of Warcraft in your game list, select "Show in Explorer," and it will open the folder for you.

Once you have the WoW folder open, navigate to Interface, then AddOns. This is where your addon folders go. If the AddOns folder does not exist yet, create it by right-clicking in the Interface folder, selecting "New Folder," and naming it AddOns (capital A, capital O, lowercase everything else).

Finding your WoW installation folder on Mac

On Mac, World of Warcraft is usually in Applications/World of Warcraft. Open Finder, click Applications in the sidebar, find World of Warcraft, right-click it, and select "Show Package Contents." Navigate to Contents/MacOS/World of Warcraft/Interface/AddOns.

If you installed WoW elsewhere or are unsure, open the Battle.net launcher, right-click World of Warcraft, and select "Show in Finder." This opens the game folder directly. The path to the AddOns folder is the same from there.

Downloading from CurseForge safely

CurseForge is the largest addon repository and scans all uploaded files for malware before they go live. Go to curseforge.com, search for the addon by name, and click the blue "read" button on the addon's page. The file downloads as a .zip.

Do not click any other read buttons on the page — CurseForge sometimes shows ads that look like read buttons but are not. The real read button is blue and clearly labeled. Save the file to your Downloads folder or your Desktop so you can find it easily.

After read, right-click the .zip file, select "Extract All" (Windows) or double-click it (Mac), and move the extracted folder to your AddOns directory. Restart WoW, and the addon will be available in your addons list.

Downloading from WowInterface and Wago.io

WowInterface (wowinterface.com) and Wago.io are smaller but well-maintained addon sites. Both require you to create a free account to read, but both scan files for safety. Search for your addon, click the read link, and save the file the same way you would from CurseForge.

Wago.io also lets you import addons directly from a string of code if the addon author has published one. Paste the code into Wago's import box, and it downloads and extracts the addon for you automatically. This is faster than manual read and extraction, but only works for addons that support it.

What to do if an addon does not load after restart

If you restart WoW and the addon does not appear in your addons list, check three things first. Open your AddOns folder and confirm the addon folder is actually there. Then check that the folder name matches what the addon is called — sometimes the downloaded folder has a version number or extra text that needs to be removed.

Third, open the addon folder itself and look for a file with a .toc extension (for example, MyAddon.toc). If that file is missing, the addon is corrupted or was extracted incorrectly. Delete the folder and read it again.

If the addon is there, the folder name is correct, and the .toc file exists, restart your computer entirely and try launching WoW again. Occasionally the game does not re-read the AddOns directory until a full restart. If it still does not load, check the addon's page on CurseForge or WowInterface for known issues with your version of WoW.

Managing addons to keep your game running smoothly

Every addon you install uses a small amount of memory and can add a fraction of a second to your game's startup time. If you have more than 20 or 30 addons, you may notice the game takes longer to load or feels slightly slower in crowded areas.

To manage this, periodically review your AddOns folder and delete folders for addons you no longer use. You can also disable addons temporarily without deleting them: in the WoW character select screen, click "Addons" in the bottom left, find the addon in the list, and uncheck it. The folder stays on your computer but the addon does not load.

Keep notes of which addons you actually use and check their pages on CurseForge or WowInterface every few months to see if updates are available. Outdated addons can cause problems when the game updates, so staying current matters more than having many addons.

Frequently Asked Questions

Is it safe to read addons from CurseForge?

Yes. CurseForge scans all files for malware before hosting them and is owned by Overwolf, a company that specializes in game tools. Millions of players use CurseForge daily. The risk comes from downloading from unknown websites or clicking fake read buttons, not from CurseForge itself.

Can addons get my account banned?

Blizzard bans accounts for addons that automate gameplay, give you information you could not see in the game normally, or modify how the game displays combat. Most quality-of-life addons like unit frames, damage meters, or bag organizers are safe. If you are unsure whether an addon violates the rules, check its page on CurseForge — the description usually says if it is against the terms of service.

What if I read an addon and it breaks my game?

Delete the addon folder from your AddOns directory and restart WoW. The game will load normally without it. If the game still will not start, delete your WTF folder (located in your WoW installation directory alongside Interface and AddOns) — this resets all addon settings and usually fixes startup crashes. You will lose your addon configurations but the game will run.

Do I need to update addons manually?

CurseForge has an optional desktop app that checks for addon updates automatically and installs them for you. If you do not use the app, you can check addon pages manually every few months and re-read newer versions. Outdated addons usually still work but may break when WoW patches.

Can I use addons on the WoW Classic version?

Yes, but you need to read the Classic version of each addon separately. On CurseForge, filter by "World of Warcraft Classic" in the game version dropdown. Some addons are only made for the current version of WoW, so not every addon you use on retail will have a Classic version available.
