# Update Share

You can append or update the content of an existing share within your Network File Storage using the `PUT` API request.

## Endpoints

Use a [<mark style="color:blue;">region-specific endpoint</mark>](https://docs.ionos.com/sections-test/guides/storage-and-backup/network-file-storage/api-how-tos/..#endpoints) to update a share: `https://nfs.{region}.ionos.com/clusters/{clusterId}/shares/{shareId}`
