This database improves performance when you browse or search for files.

Cache preferences help you manage the trade-off between performance and cache size.

Choose Edit Preferences Cache (Windows) or Bridge Preferences Cache (Mac OS) and choose from among the following options.

This zoom-in is what you see in a slideshow and in full-screen preview.

It is also what you see when you use the Loupe tool in Review mode or the Preview panel.

When you use this cached file, you avoid rerendering a 100 image from the original source file.

However, it does require additional disk space and initial processing takes some time.

The Keep 100 Previews In Cache option allows the 100 preview to be written to the central cache, which is in the following location.

See Show hidden files, folders, filename extensions Windows XP, Vista, Windows 7.

These full-size previews are only used for 100 zoom and loupe, however.

Also, they arent used in the Preview panel or Review mode when you are not using the Loupe tool.

It generates exported cache files for every folder that Adobe Bridge browses (as long as the folder is not read-only).

The first time Adobe Bridge views a folder, it checks for the existence of an exported cache.

If it finds an exported cache, Adobe Bridge imports all the entries into its central cache.

After that, Adobe Bridge only deals with the central cache for that folder; any new or modified thumbnails or metadata is stored in the central cache.

If Automatically Export Cache To Folders When Possible is selected, Adobe Bridge also updates the exported cache with the newly generated or updated thumbnails or metadata.

But Bridge does not read exported cache data for that folder since the folder exists in the central cache.

What does this mean in practice It comes into play when multiple instances of Adobe Bridge -- on the same or different computers -- view the folder.

And because Automatically Export Cache To Folders When Possible is selected, it updates the exported cache file.

It generates thumbnails for the new files and adds them to the central cache.

You can export the cache manually for any individual folder by choosing Tools Cache Build And Export Cache.

You could do this step, for example, before burning a folder to DVD.
