Files

The Dolfin files tree in the sidebar lists the project’s files. package.dlf is not in it: edit it through ⚙ Package.

A file opens in the editor that matches its extension:

Extension	Editor
`.dlf`	The Dolfin editor.
`.ttl`, `.turtle`	The Turtle editor.
`.md`	A plain Markdown editor, handy for notes and a README.

Button	Action
Collapse all	Folds every folder.
Import	Files… takes any mix of `.zip`, `.dlf` and `.md` files; Folder… takes a whole folder, read recursively. Everything lands at the package root: a folder `foo/` becomes `foo/...` with its subfolders kept, and a zip found in a folder is unpacked where it sits. Hidden files (`.git/`…) and other file types are skipped, and a notice lists them. If some names already exist, Agrafe asks whether to Overwrite all, Skip conflicts or Cancel.
Export as zip	Downloads every file of the project, `package.dlf` included, as `<package name>.zip`.
+	Creates a new file at the top level.

The number of files per project depends on the owner’s plan.

Folders

Folders come from file names: a file named models/person.dlf sits in a models folder. A folder disappears when its last file goes.

Hover a folder for two buttons: + (new file in that folder) and a hold-to-delete trash that removes the folder and every file in it.

Right-click a file:

Item	Action
✏ Rename	Edits the file name in place. Only the name is edited; the file stays in its folder. `Enter` confirms, `Escape` or clicking away cancels.
⟳ Re-translate to Dolfin…	Only on the origin `.ttl` of a Turtle project. See Re-translate.
Delete	Deletes the file at once.

Right-click a folder:

Item	Action
+ New file here	Creates a file in that folder, ready to be renamed.
Delete folder	Deletes the folder and all its files.

The same file actions also exist on hover: a pencil (Rename, also F2) and a hold-to-delete trash.

Renaming a Dolfin file changes its namespace, so the IRIs of everything declared in it change too.

A file with problems shows its error and warning counts next to its name. The Problems panel lists them.
In a project imported from Turtle, the original file carries an origin badge and stays at the top. Deleting it asks for confirmation, because Reveal and sync depend on it. See Importing a Turtle file.

The tree is a single stop in the tab order. Once it has focus:

Key	Action
`↑` / `↓`	Previous / next row.
`Home` / `End`	First / last row.
`→`	Opens a folder, then moves into it.
`←`	Closes a folder, or moves to the parent folder.
`Enter`	Opens the file, or toggles the folder.
`Space`	Toggles the folder.
`F2`	Renames the file.
