Notebook folders

Group your notebooks into folders, as you can with workspace folders in Fabric and Databricks. A folder is part of a notebook's name: Sales/Daily load is the notebook Daily load in the Sales folder. On disk it is Sales/Daily load.ipynb in the notebooks folder of the place it's saved in (the app's own folder, or a notebooks repository's notebooks folder). Its resources are in Sales/Daily load.resources/ beside it.

Nothing here replaces or deletes a notebook, and nothing in Fabric changes.

See notebooks by folder#

On All notebooks (Home, under Recent notebooks), notebooks are grouped by folder once you have one. Each folder shows how many notebooks it holds, counting its subfolders, and folds with its arrow. Notebooks in no folder are under Not in a folder. When you have notebooks repositories, a folder shows which place it's in, and the Saved in chips filter folders too.

In a notebook, the explorer's Notebooks tab shows the same folders, so you can open another notebook without leaving it.

New folder#

New folder on All notebooks makes an empty folder. When you have notebooks repositories, pick the place to make it in. Type Sales/Archive to make a folder inside another, or use New folder inside… on a folder's ⋯ menu.

• Folders go 3 levels deep. A notebook's name can be Sales/Archive/2026/Q1 backfill, no deeper.
• Each folder name follows the notebook name rule: no < > : " \ | ? *, and no dot at the end. A folder name can't start with a dot, and can't end with .resources, which is where a notebook keeps its resources. Names Windows keeps for devices (CON, PRN, AUX, NUL, COM1 to COM9, LPT1 to LPT9, with or without an extension, in any case) can't be a folder or notebook name.

New notebook here, on a folder's ⋯ menu, makes a new notebook in that folder (Sales/Notebook 1).

Move a notebook to a folder#

On All notebooks, a notebook's ⋯ menu has Move to folder…. The command bar (Ctrl+K) also finds Move this notebook to a folder for the open notebook. Pick a folder in the notebook's place, or Not in a folder. Moving it is a rename, so what goes with a renamed notebook goes with this one:

• its resources folder, which moves beside it;
• its versions, comments and session;
• this PC's schedules that run it, which run it by its new name;
• its environment and its link to its Fabric item.

If the folder already has a notebook with that name, nothing moves. To move a notebook to another place (a notebooks repository), use Move to another place…; it keeps its folders there.

Rename a folder#

Rename folder… on a folder's ⋯ menu renames it where it is. The folder is renamed on disk with everything in it, so each notebook in it gets its new name (Sales/Daily load becomes Sales EMEA/Daily load), and its versions, this PC's schedules, session, environment and Fabric link follow it. If a folder or notebook with the new name is already there, nothing is renamed.

Delete a folder#

Delete folder… deletes a folder only when it's empty. A folder with notebooks in it can't be deleted: move or delete them first. A folder with anything else in it (another folder, a file, or the resources folder of a deleted notebook) can't be deleted either, and the message says what's in it. This way no notebook is ever deleted with a folder. Deleting an empty folder asks once.

Recently deleted#

A notebook deleted from a folder keeps its whole name in Recently deleted. Restore puts it back in that folder, making the folder again if it was deleted meanwhile.

Publishing a notebook from a folder (Preview)#

Fabric names its notebook item after the notebook's own name, without its folders: Sales/Daily load publishes as Daily load. KratosForge doesn't make or use Fabric workspace folders, so the item goes where Publish has always put it. Moving a notebook into a folder or renaming its folder keeps its Fabric item, because the item's name doesn't change.

Two notebooks in different folders can have the same name, but they can't both publish to one workspace: Publish stops, nothing is sent, and the message names the notebook already linked to that item. Rename one of them, or publish it to another workspace.

This hasn't been tried on a live tenant yet, so it's marked Preview.

How this works#

Every write, in one place. In a notebooks repository each shows as a change to commit.

If something kept by a notebook's name can't follow it (its session, environment, Fabric link, versions or this PC's schedules), the notebooks still move, every other step still runs, and a warning names what didn't follow and what to do about it.

Known limitations#

• The check before publishing that two notebooks would share one Fabric item only sees notebooks linked to an item from this PC. A notebook published from another PC, or an item made in Fabric, with the same name is replaced by Publish as before.
• Renaming a folder changes only its last part; a folder can't move to another parent folder.
• A notebook in Recently deleted keeps the folder it was deleted from, so restoring it after that folder was renamed makes the old folder again.
• Fabric workspace folders aren't used.

Fabric schedules belong to the Fabric item, so they don't change when a notebook moves. A notebook in a folder isn't searched any differently: search on All notebooks finds it by its whole name.
