Adobe Bridge Cache File

A BC file may also be a file browsing cache created by Adobe Bridge, a program for managing files with Adobe Creative Cloud (CC) applications. It contains metadata automatically generated by the application when a user browses images to summarize image information more quickly during browsing.

BC files are saved with .BCT files, which store image thumbnails for the cache. Adobe Bridge's cache files may be either centralized or distributed, meaning they are stored in one location or distributed to every folder being browsed. Users can set the caching option in the software preferences.

NOTE: It is safe to delete BC and BCT files from your hard drive. However, Adobe Bridge will regenerate them the next time you preview files in the application.

Adobe Bridge Cache.bc - Default name Bridge gives to BC cache files.

You should not attempt to open BC files. Instead, Adobe Bridge references the metadata in the file and displays it when browsing assets with Bridge.

OpenTerrainGenerator Biome Configuration

A BC file may also be a biome configuration file created by OpenTerrainGenerator, a Minecraft modding application used to create custom worlds. It contains plain text data that defines a biome's settings, as well as the custom structures ( .BO4 or .BO4DATA files) the biome includes. BC files can be opened and edited in any text editor.

Minecraft Java Edition players can install the OpenTerrainGenerator plug-in and use it to create and load custom Minecraft worlds. Each OpenTerrainGenerator world is generated using one or more BC files. Each BC file defines a biome that a custom world contains.

Each section of a BC file controls a specific aspect of the biome generation process. For example, the BiomeSize: setting controls the biome's size, the BiomeHeight: setting controls the biome's height, and the BiomeVolatility setting controls how hilly the biome is. Creators can control most aspects of how the biome appears, what structures it contains, and what objects it contains using the biome's BC file.

Each world's BC files are stored in that world's WorldBiomes directory. OpenTerrainGenerator also uses a GlobalBiomes directory, which can contain

You can open and edit a BC file in any text or source code editor, such as Microsoft Visual Studio Code (cross-platform). Keep in mind that editing a BC file's settings may break the biome the BC file defines.
