I enabled the default encryption module in my Nextcloud instance. As the docs mentioned, I noticed while the contents of files are encrypted, your cloud service provider can see the file names/directories (!). This is a bit disappointing, since that kind of metadata should have been encrypted too.
Is there a technical reason for the filenames and directory structure to not be encrypted (I can think of ways this could have been done - such as by maintaining an encrypted “map” of filenames and directories)?
Any workaround for this thing?
