.toc (Table of Contents) files contain information about a particular addon (such as its name, description, saved variables, etc), as well as instructions on how the addon should be loaded by the client (for example, the order in which lua and xml files should be loaded). The file must be present, and have the same name (plus extension) as its parent folder for the addon to be recognized by the client.

Basic rules

The .toc file and addon folder name need to match, e.g. ..\Interface\AddOns\MyAddon\ and MyAddon.toc

The file may contain the following elements:

  • Metadata as ## Directive: Value
  • Comments as # this is a comment
  • A list of files as myFile.xml or subfolder\anotherFile.lua

Whitespace before # will be interpreted as the start of a filename. However, the client trims whitespace around metadata values (after the colon).

Backslashes (\) are recommended for subdirectories to prevent issues with <Include> tags.

## Interface: 90205
## Title: Waiting for Godot
## Notes: Nothing to be done.
## Version: 1.0

# This line is a comment

Multiple client flavors

Classic and retail versions of the game can be properly supported by including multiple TOC files in the same addon.[1] The client first searches for the respective suffix and otherwise falls back to AddonName.toc

Flavor Suffix
Shadowlands Retail AddonName_Mainline.toc
Wrath of the Lich King Wrath of the Lich King Classic AddonName_Wrath.toc
Bc icon.gif Burning Crusade Classic AddonName_TBC.toc
WoW Icon update.png Classic Era AddonName_Vanilla.toc
  • Clients also recognize legacy suffixes -WOTLKC, -BCC, and -Classic.
  • It's recommended to simply use AddonName.toc for retail since CurseForge otherwise will not accept the zip.

File load order

The .toc file provides an ordered list of files to be loaded by the client. In the earlier example:

  • Vladimir.xml loads first, and is in the same folder as the .toc file
  • Estragon.lua loads second, and is in the same folder as the .toc file
  • SomeLibrary.lua loads third, and is in a subfolder called libs

Not every file must appear in a .toc list:

  • XML files may contain <Script file="nameOfAnotherFile.lua" /> or <Include file="alsoLoadThis.xml" />
  • Texture:SetTexture() and PlaySoundFile() can use images and sounds contained within the addon folder and its subfolders

Interface version

## Interface: 90205

The interface metadata specifies which version of the game client the addon has been made for. This field prevents users from experiencing errors by loading out-of-date addons or mixing Retail and Classic; unless they explicity ignore warnings and choose "Load out of date addons". Omitting this field causes the game to treat the addon as always out of date.

There are a number of ways to get the current interface version:

It probably is 90205 (retail), 20504 (bc classic) or 11403 (classic)
But these numbers are maintained locally, so they might be out of date.
Use GetBuildInfo
In particular, /dump select(4, GetBuildInfo()) should output the correct version to your chat frame.
Steal it from another AddOn
Recently updated AddOns, which are not listed as "out of date" by the client contain the latest Interface version in their toc.

Prior to patch 8.2.0:

Extract FrameXML and check FrameXML.toc
Launch wow with the -console flag, then at the login screen, activate the console using the `/~ key, and type ExportInterfaceFiles code to extract FrameXML files into World of Warcraft\BlizzardInterfaceCode.
View FrameXML.toc online
For instance at wowcompares.

AddOns list formatting

The following directives change how an AddOn appears in the AddOns list. Both may be coloured using UI escape sequences (e.g. |c########|r), or localized by appending a hyphen and the locale code (e.g.Title-enGB). Later entries overwrite earlier ones, so the non-localized fallback should go first.


Name displayed in the AddOns list.
## Title: Waiting for Godot
## Title-frFR: En attendant Godot


Tooltip displayed in the AddOns list.
## Notes: This word is |cFFFF0000red|r

Loading conditions

The following directives control when an AddOn loads, and any dependencies that must or may load first.


1 to delay loading until LoadAddOn().
## LoadOnDemand: 1


AddOns that must load first. Aliases include RequiredDeps and any word beginning with Dep.
## Dependencies: someAddOn, someOtherAddOn


AddOns that should load first if available.
## OptionalDeps: someAddOn, someOtherAddOn


AddOns that, once loaded, trigger this one to load. Implies LoadOnDemand. Warning Warning: Currently broken on Classic - Issue #223.
## LoadWith: someAddOn, someOtherAddOn


AddOns that, if present, trigger this one to behave as LoadOnDemand. See AddonLoader for an example.
## LoadManagers: someAddOn, someOtherAddOn


disabled to require the user to explicitly enable the AddOn in the AddOns list.
## DefaultState: disabled

Saved variables

Main article: Saving variables between game sessions


Variables saved in WTF/[account]/SavedVariables.
## SavedVariables: foo, bar


Variables saved in WTF/[account]/[server]/[character]/SavedVariables.
## SavedVariablesPerCharacter: anotherVariable


The following metadata may be accessed using GetAddOnMetadata().

The AddOn author's name, displayed
The AddOn version. Some automatic updating tools may prefer that this string begins with a numeric version number.
Any custom metadata prefixed by "X-", such as "X-Date", "X-Website" or "X-Feedback"


The following tag is inaccessible to third-party AddOns.

1 with Blizzard's digital signature to indicate a secure AddOn.


  • WoW reads up to the first 1024 characters of each line only. Additional characters are ignored and do not cause an error.
