Adobe Bridge - storage limits

Bridge is not "just a file browser." For each image file in a folder it generates up to three derivative files, depending on your settings: a preview image, a 100 percent preview image, and a thumbnail image. These are stored in a central cache folder that can take up considerable space, or can be stored "locally" (in the same folders as the images being browsed). Previous versions of Bridge limited the number of cache files to 500,000. Bridge 2021 (Version 11) limits the cache size to around 52 gigabytes. The upshot of all this is that for folders with thousands of large image files, it can take days for Bridge to generate a complete set of thumbnails and previews. To keep under the 52 GB (or 500,000-file) limit, Bridge will occasionally delete an entire folder of cache files, which can make for very slow folder browsing as well as cause a lot of disk churn and long save times in your storage array.

Absolutely None. Bridge is a Free program that does not need the user to subscribe to any subscription plan.

It is also just a File Browser, File Manager.

It can not do any edits to any file, other than standards File Manager task, without some other program like PS, CR, ID and so on. And even then 99% of the time it only Send whatever file to one of those programs. It does Not edit them itself.
