 - Modifying an existing project in the Data Exchange is permanent and cannot be undone. 
 - For projects that originated from the Data Exchange, a comprehensive file hash check is used to determine which files have changed relative to those that already exist online. Only files that have changed are uploaded.
-- Note that the simple act of adding a GeoPackage layer to the map in QGIS will ever so slightly change the underlying GeoPackage file on disk. This means that downloading, viewing and then re-uploading a Riverscapes project will likely detect changes in GeoPackages that have been used, even if you haven't explicitly made any changes to the data. This is a limitation of the GeoPackage format and not a bug in the uploader. Given that most Riverscapes project types have a [default project view](https://viewer.riverscapes.net/technical-reference/business-logic/#project-views) that loads one or more GeoPackage layers into the map, this is a common scenario. The uploader will detect these changes and upload the modified GeoPackages. This is not a problem, but it is something to be aware of.
