I know exactly what this person is talking about and they are not getting the right answer.
I recently found out that I am using 350mb of storage on my ipad for Dropbox.
I have nothing favourited.
Now, I want to KEEP the files on DropBox as they are NOT suppose to be using storage on my iPad. So, I wish to keep them on there, and keep the App so I can "view" the images from the image on the DP server.
However, I am told by Dropbox that the App basically caches it like Safari/IE does. On Windows you can view the cached images and delete them. How do you do this on iOS?
Once again: I do not want to delete the images on Dropbox, just the cache.
