# Edit virtual file systems

Virtual file systems listed in **Setup** → **Virtual File Systems** can be edited or deleted using the menus available through the 3-dot icon on the right side of each entry:

* **EDIT** – Modify the configuration of the VFS.
* **DELETE** – Remove the VFS, if allowed.

#### When a **virtual file system** or virtual path cannot be deleted

Certain conditions prevent the deletion of a Virtual File System or its virtual paths. When one of these conditions applies, Data Mover displays a warning message explaining why the operation cannot proceed.

* **VFS or** virtual path **used in a VFS View**: a VFS or virtual path cannot be deleted if it is referenced by a **VFS View**. \
  A warning message will indicate that it is in use and will name the affected VFS View.
* **Virtual path used in a Connection Contract**: if a virtual path is referenced in one or more **Connection Contracts**, it cannot be removed from a VFS or a VFS View.\
  The warning message lists every Contract using that virtual path.
* **Virtual path linked to a Connection Contract**: a virtual path cannot be deleted from a View if it is associated with a **Connection Contract** built on that View. The warning message lists every  Connection Contracts using the virtual path.
* **Virtual paths linked to Contracts**: any virtual path that is linked to a Contract cannot be deleted.
* **Non‑empty virtual paths**: a virtual path containing one or more files cannot be deleted.
* **VFS containing files**: a VFS that has files stored in any of its virtual paths cannot be deleted.
* **VFS with virtual paths attached to Contracts or Connections**: a VFS cannot be deleted if one or more of its virtual paths are attached to a **Contract Connection** or to a **Contract**.
