Files stored in folders in Firebase storage can be retrieved by just adding the full path in “file” in the download block of the Firebase Storage Component, where the file name is specified.
For the question you asked at the beginning of this discussion, what you’ve marked is not the solution. Having the files in folders is not a problem. In fact, we may need to arrange them in folders. So what you suggested is not a solution.
The solution is that you just have to enter full path name of the folder you want the image to be downloaded.(Eg. /storage/emulated/0/Download to store the file in ‘Download’ folder in the mobile internal storage) I use this in my projects and works perfectly!
