I'm not familiar with FME, so normally I only use auto-generate.

Because I need to extract the filename and put it as an attribute in the shp file, so I try to add the transformer like this.

But the ouput file is duplicate data like this

In your dataflow you have split the data into two streams so you are writing each feature twice.

To fix:

  1. Remove the connection between your reader and the geometryfilter.

  2. Change the output of the filename extracter to connect into the geometryfilter.
