.BRIDGECACHE File Extension

Cache file generated by Adobe Bridge, an Adobe Creative Cloud (CC) file management application; contains exported metadata for the files held in the same folder; similar to .BCM, .BC, and .BCT files.

To create a BRIDGECACHE file:

1. Navigate to the folder you'd like to build a cache file.
2. Select Tools → Cache → Build and Export Cache....
3. Then, to view your BRIDGECACHE file, select View → Show Hidden Files.

Cached files like BRIDGECACHE files can also take up storage space, so to remove them navigate to their folder and select Tools → Cache → Purge Cache For Folder "foldername".
