Tips

• View all stored files: filesystem: https://app.quackdb.com/temporary. To navigate, manually change the URL to the desired path as Chrome does not allow navigation by clicking on the links.

Known Issues

• Safari will not be supported until this bug is fixed (serializing file handles is not supported in Safari).
