How to search file inside a specific folder in google API v3

As i am using v3 of google api,So instead of using parent and chidren list i have to use fileList, So now i want to search list of file inside a specific folder. So someone can suggest me what to do?

Here is the code i am using to search the file :

private String searchFile(String mimeType,String fileName) throws IOException{
    Drive driveService = getDriveService();
    String fileId = null;
    String pageToken = null;
    do {
        FileList result = driveService.files().list()
                .setQ(mimeType)
                .setSpaces("drive")
                .setFields("nextPageToken, files(id, name)")
                .setPageToken(pageToken)
                .execute();
        for(File f: result.getFiles()) {
            System.out.printf("Found file: %s (%s)\n",
                    f.getName(), f.getId());
            if(f.getName().equals(fileName)){
                //fileFlag++;
                fileId = f.getId();
            }
        }
        pageToken = result.getNextPageToken();
    } while (pageToken != null);

    return fileId;
}

But in this method it giving me all the files that are generated which i don't want.I want to create a FileList which will give file inside a specific folder.

To search in a specific directory you have to specify the following:

q : name = '2021' and mimeType = 'application/vnd.google-apps.folder' and '1fJ9TFZOe8G9PUMfC2Ts06sRnEPJQo7zG' in parents

This examples search a folder called "2021" into folder with 1fJ9TFZOe8G9PUMfC2Ts06sRnEPJQo7zG

In my case, I'm writing a code in c++ and the request url would be:

string url = "https://www.googleapis.com/drive/v3/files?q=name+%3d+%272021%27+and+mimeType+%3d+%27application/vnd.google-apps.folder%27+and+trashed+%3d+false+and+%271fJ9TFZOe8G9PUMfC2Ts06sRnEPJQo7zG%27+in+parents";

It is now possible to do it with the term parents in q parameter in drives:list. For example, if you want to find all spreadsheets in a folder with id folder_id you can do so using the following q parameter (I am using python in my example):

q="mimeType='application/vnd.google-apps.spreadsheet' and parents in '{}'".format(folder_id)

Remember that you should find out the id of the folder files inside of which you are looking for. You can do this using the same drives:list.

More information on drives:list method can be seen here, and you can read more about other terms you can put to q parameter here.

You can use this method to search the files from google drive:

Files.List request = this.driveService.files().list();
noOfRecords = 100;
request.setPageSize(noOfRecords);
request.setPageToken(nextPageToken);
String searchQuery = "(name contains 'Hello')";
if (StringUtils.isNotBlank(searchQuery)) {
    request.setQ(searchQuery);
}
request.execute();

Searching files by folder name is not yet supported. It's been requested in this google forum but so far, nothing yet. However, try to look for other alternative search filters available in Search for Files.

Be creative. For example make sure the files within a certain folder contains a unique keyword which you can then query using

 fullText contains 'my_unique_keyword'
