Set cache preferences

Select Edit > Preferences (Windows) or Adobe Bridge > Preferences (macOS).

In the Preferences dialog box that opens, select Cache.

Select one of the following:

• Cache Size: Drag the slider to specify a larger or smaller cache size. The default cache size is 100,000. If the cache is near the defined limit (500,000 records) or the volume that contains the cache is too full, older cached items are removed when you exit Adobe Bridge. The larger cache improves performance, but consumes more disk space. Under Edit > Preferences > Cache, you can now set the maximum amount of disk space to be used for cache in gigabytes using the Cache Size slider.
• Compact Cache On Exit: If selected, automatically compacts cache when you close Adobe Bridge if cache database size grows beyond 100 MB. Recommended to keep your cache optimized. However, if the preference for compacting cache is not set and the cache database size grows beyond 100 MB on your machine, a dialog box is displayed when you quit Bridge.
• Keep 100% Previews In Cache: Keeps 100% previews of images in the cache to speed zoom operations in a slideshow or in full-screen preview, and when using the Loupe tool. Keeping 100% previews in cache, however, can use significant disk space.
• Automatically Import Cache From Folder When Possible: Imports the cache automatically when you browse the folder containing the exported cache. The auto import of cache files improves the performance.
• Purge Cache Older Than 'N' Days, When Bridge Is Idle: Specify the purge duration (between 1 day and 180 days). Previously cached items that are older than the specified days are considered as stale and automatically removed when Bridge is idle.

Select OK.
