# Search for files owned by the current user
#
# Returns a [FileList](https://github.com/googleapis/google-api-ruby-client/blob/main/generated/google-apis-drive_v3/lib/google/apis/drive_v3/classes.rb)
# object. The FileList object has a `files` property that is an array of files returned.
#
# This example illustrates how to:
#   1. specify a search query (to omit files in the trash)
#   2. specify which fields to return for each file
#   3. retrieve pagenated results
#
# Use the `jq` command to format the output of this script. For example:
#   * List names: `bundle exec examples/list_files | jq '.[].name'`
#   * List names and id's: `bundle exec examples/list_files | jq '[.[] | {name: .name, id: .id}]'`
#   * List names and parents: `bundle exec examples/list_files | jq '[.[] | {name: .name, parents: .parents}]'`

# By default `list_files` returns all files even files in the trash. To omit trashed
# files add `trashed=false` to the q (query) parameter.

# for more information about how to use the `q` parameter.

# If `fields` is not specified, the following fields are returned for each file:
# id, name, mimeType, and kind.
#
# Could return all possible fields by specifying `fields: '*'`. In this example,
# we only need `nextPageToken` for the request and `id`, `name`, and `parents`,
# and `web_view_link` for each file.
#
# If you give fields, you must explicitly include `nextPageToken` if you want it.
#
# See [Return specific fields for a file](https://developers.google.com/drive/api/guides/fields-parameter)
# for more information about how to retrieve other fields.
