Hi all

I have an FME Workbench file which has to do the following things:

  1. Ask for multiple directories via a published user parameter
  2. read two files in each directory which end in _changes.shp and _to_remove.shp AND are always located in a subfolder v1 in each directory.

The transformers and writer after that are already doing what they should do, but I can’t seem to confgure my reader to do what I asked here. Is this even possible to do? And if so, how should I do this?

Thanks in advance for the help!

Adding a PATH Reader to the workspace will automatically add a Multiple Folder User Parameter to the workspace as well.

The User then can select Multiple Paths when the workspace is Run 
 

 

The Writer needs a small tweak, to turn Subfolder Recursion to Yes, and can put in an initial filter at least to only return File Paths rather than Folder Paths.  The Path Filter could optionally also be set to *.shp but going to do that in the next Tester step anyway.
 


So then can flow all these File Paths into a Tester to find which meet the file filtering rules
 



and can then send these filtered file paths to a SHP FeatureReader
