Files

Stalwart stores files as JMAP FileNodes, and Bulwark browses them. Documents and media end up in the same interface as the mail and the calendar, rather than in a separate app you have to remember to open.

File browser

  • Folder tree navigation with breadcrumb path over a real FileNode hierarchy
  • Grid and list views
  • Sorting by name, size, or date
  • Favorites and recent files for quick access
  • Bulk multi-select actions
  • Right-click context menu

Upload and download

  • Upload individual files with progress tracking
  • Folder upload via drag-and-drop or toolbar button (recursive)
  • Streamed WebDAV PUT - uploads stream straight to the server without buffering the file in memory, so multi-GB uploads work in browsers with limited memory
  • Download files or entire selections
  • Dynamic upload size limits read from the server's configuration so the UI knows what's allowed before you try
  • Clipboard-style cut, copy, paste, and duplicate actions
  • Drop zone fills the available viewport height for easy bulk drops
  • Falls back to application/octet-stream for files with unusually long MIME types

Warning Stalwart's FileNode storage is still maturing. Very large uploads can occasionally cause server instability, and deleted files may not be immediately purged from storage. Use with caution in production deployments.

Preview

  • Images (JPEG, PNG, WebP, GIF, SVG)
  • Text (plaintext, source code with syntax highlighting)
  • Audio
  • Video
  • PDF (in a sandboxed iframe with strict CSP)

Organization

  • Create, rename, move, and delete folders
  • Files are stored as real FileNode records in a nested hierarchy; folders are detected as blob-less nodes and listed via FileNode/get
  • Legacy installs that stored files under flat, slash-encoded names are migrated into the proper folder hierarchy automatically on first load
  • Quick metadata visibility for size and modified date
  • Recent files prune themselves automatically when underlying nodes are deleted on the server

Integration

  • Native JMAP FileNode support in Stalwart
  • Unified authentication and permissions with the rest of Bulwark
  • Per-account isolation when multiple accounts are connected
  • Attachments and stored files sit one click apart, so moving between them doesn't mean changing apps
