# Configure VFS options

The VFS browser can be configured to set variables as parameters for use at runtime. A `VFS Configuration Sample.ktr` sample transformation containing some examples of the parameters you can set is located in the `data-integration/samples/transformations` directory. For more information on setting variables, see [Specifying VFS properties as parameters](https://github.com/pentaho/documentation/blob/main/PDIA/9.3/PDI/Data%20Integration%20Perspective/Data%20Integration%20perspective%20in%20the%20PDI%20client/Advanced%20topics%20\(PDI%20perspective\)/PDI%20run%20modifiers/Parameters/VFS%20properties/Specifying%20VFS%20properties%20as%20parameters=GUID-1AFFCB92-45CC-43DB-BFB5-9F50E8451FB7=3=en=.md).
