Hi @vincenzos1984 :
Do you want to get a list of files that in the sub-folders(Piacenza/ Bologna) in this folder('Giacenze')?
If my understanding is correct, I suggest you try this code:
Filter('Giacenze',("Piacenza" in 'Full Path'||"Bologna" in 'Full Path') && IsFolder=false)
The point is we can distinguish the parent folder of the files by using 'Full Path' .
When you call 'Giacenze', the app will retrieve all files in the 'Giacenze' folder (including files in subfolders) and return them as a list. So we need to determine whether they are in the folder we need by the location of the file. In this case, using the 'Full Path' field is a good choice.
Best Regards,
Bof
