Description of Changes Adds folder kinds so the file manager can work with real directories on disk. Desktop - New folder is now a menu with two options: "Add local folder" and "New folder on the server". - Add local folder opens the native picker and mounts a directory. Files are listed straight from disk, nothing is copied in. - Subfolders show inside a mount and open like any folder. New folder inside a mount creates a real directory on disk. - Moving, dropping or uploading files into a mount writes them to the directory. The app copy is only removed after the write succeeds. Name clashes get a " (2)" suffix. - Mounted files get thumbnails. - Adding the same directory twice just returns the existing mount. - Removing a mount never touches the disk. - The server option is disabled in local mode with a sign in message. Web + desktop - Uploading or dropping files while inside a folder puts them in that folder instead of Local. - Files can be dragged onto folders in the grid and the tree to move them. - Folders show an origin badge (cloud or local). - The Local view now means files that are not in any folder. Follow ups for a future pr - Mount listing cap: large directories currently show the 500 most recent files with no notice. Will be removed as part of the virtualisation/performance PR. - Folders within folders need to be supported - Symlinks in mounts: currently not listed. Behaviour to be decided alongside the wider folder work.
