# Delete an SFS

Deleting an SFS removes its storage and every file on it for good, and stops billing for it.

## Before you begin

- The **Dataset** permission in your project policy. SFS shares this permission with Object Storage, Block Storage, and
  Parallel File System.
- Copies of any files you need, kept somewhere else, such as TIR Datasets or storage outside TIR.
  Deleting an SFS is permanent.
- The SFS unmounted from every instance and out of use by every active training job. If it is
  still in use, the delete is refused with a list of the instances or jobs using it. See
  [Mount an SFS on an instance](/tir/tir-sfs/how-to/mount-an-sfs-on-an-instance/).

## Delete the SFS

1. In **Manage Shared File-System**, open the SFS's **Actions** menu and select **Delete
   File-System**.
2. Tick "I understand and want to delete file-system `<name>`.", where `<name>` is the SFS's name.
3. Select **Delete**.

The SFS leaves your list. Deleting an instance or a training job works differently: any SFS it had mounted stays
in the list, ready to mount elsewhere, until you delete it yourself.
