Using Google Drive API with Java, how to list only files in the Drive Section/Folder

Question

I am trying to get all files that are in a specific section of Google Drive (The Drive Section).

Those are the files I am looking for:

You can see a folder named Projet 3 and a file named Processus TP2 questions. In the folder I only have one file.

But when I try to list all the files, I get thousands of files. If I search for them using the search bar on top of Google Drive, it finds them, but I have no idea where they are (maybe Gmail attachement?).

This is my search query:

FileList result = service.files().list()
    
    .setQ("mimeType != 'application/vnd.google-apps.folder' 
            and trashed = false")
    
    .setSpaces("drive")
    .setFields("nextPageToken, files(id, name, parents)")
    .setPageToken(pageToken)
    
    .execute();

How can I list only the files I can see in my Drive Section/Folder on the web UI?

Thank you very much.

Use "parents" property in your query, like this:

FileList result = service.files().list()
    
.setQ("'root' in parents and mimeType != 'application/vnd.google-apps.folder' and trashed = false")
    
.setSpaces("drive")
.setFields("nextPageToken, files(id, name, parents)")
.setPageToken(pageToken)
    
.execute();

If you want to list the contents of a specific folder rather than root - use that folder's id instead of 'root' in the query.
