.ARC File Extension

ARC files were commonly used in the late 1980s and early 1990s. However, they are rarely used now and have been replaced by newer, more efficient compression algorithms.

NOTE: While ARC files were used primarily for MS-DOS and older versions of Macintosh computers, several current programs can still open them, such as StuffIt and WinZip.

The DATA.ARC file is referenced by the African Safari game and should not be manually opened by the user.

Example ARC files include backup.arc, Messages.arc, Calendars.arc, and Bookmarks.arc.

In the past, developer 4J Studios published console-specific versions of Minecraft. These versions of Minecraft were named for the console on which they could be played. For example, the PlayStation Vita version of Minecraft was named Minecraft for Playstation Vita.

Players often refer to these versions of Minecraft, which have since been replaced by Minecraft Bedrock Edition, as Minecraft: Legacy Console Edition. All Minecraft: Legacy Console Edition games include ARC archives. While players are not meant to open or edit these files (or the game data they contain), Minecraft: Legacy Edition modders have created tools that allow them to extract assets from and add assets to ARC files.

You can open and manage ARC files with ARC Studio (Windows) or MCCToolChest (Windows).

Both WWE 2K18 and 2K19 cache certain game data to speed up the games' startup time. The games store this cached data in and load it from Chunk0.arc.

Most WWE 2K18 and 2K19 players will never encounter or need to modify Chunk0.arc. However, modders who have installed 2K18 or 2K19 mods must delete or clear Chunk0.arc, to clear the games' cache so their installed mods load correctly. Otherwise, the games will crash at startup.

Chunk0.arc is not meant to be opened.

You can open an ARC file with Webrecorder Player (multiplatform). Doing so will allow you to view the archived content the ARC file contains.
