What is format of Google Drive's FileID ? I need to find out whether new File has been uploaded to my drive or not using API's

Question

If FileID follows a particular format like new file has higher values or lower values I can keep track of the old values and find out whether I hace uploaded a new File in drive.

Answer 1

File ID is just a random string - there is no format.

You are taking the wrong approach. Look at the changes resource https://developers.google.com/drive/v3/reference/changes
