In Windows Explorer, clicking on the down arrow while holding down the CTRL key will collapse that folder and all of its subfolders. This feature has also been implemented in Dreamweaver. It would be helpful to have this feature in Bridge also. Currently, the only way to collapse all folders is to quit and restart Bridge.
On my site there are well over 1,000 folders and subfolders on three drives drives, including many A, B, C, ... X, Y, Z folders nested five levels deep. After several additions or edits, the folder list in the Folders pane gets very long, requiring several folders to be manually closed just to make navigating easier.
This is a good suggestion but not a good location for letting Adobe know about it.
A much better place is: https://adobebridge.uservoice.com/
These forums are intended for folks to ask questions on how to do things, issues that they may be having, etc.
Gary. Thanks for the suggestion. I just now did that.
