# Update bytes in-place using fileUpdate

As of **2023-07**, you can use the `fileUpdateInput` to provide an originalSource which will be used to update the bytes of a file. Passing originalSource when updating is supported media images and generic files.

Using this functionality makes it easy to do an in-place update of an existing file.
