Where bridge save the data - information stored (not the image cache)?

Thank you for your answers, they have been of great help to me.
If I need to format my computer I should not save anything except the files in question since the information is integrated into the metadata of each classified file.

Although I am seeing that in webp files it cannot record metadata when putting it in a collection it saves it in the data folder suggested by @Stephen Marsh
and when I open the collections file I see that it saves the path of each image in the collection (full path from the root drive)

I have changed the location outside of Bridge and see that the behavior is similar with Lightroom with the redirection of unlinked elements in its databases.

If you are referring to manual sort order, there is a hidden/invisible file called .BridgeSort in each folder that has manual sorting.

If you are referring to where assets such as collections, smart collections and other assets are stored, it depends.

For example, on the Mac, many assets are found in:

/Users/username/Library/Application Support/Adobe/Bridge 2024/

While for Windows it is:

C:\Users\username\AppData\Roaming\Adobe\BridgeBridge 2024\

However, it will depend on the asset and it may be in another location, you need to be specific.

You are correct; there is no catalog in Bridge. When you open a folder and select it in Bridge, Bridge just sees what there is to see in that folder. Any of the labels, ratings, etc., become part of the metadata in the file, and Bridge views that. 

If you want a catalog filled with data about your files, you need to use Lightroom Classic.
