This is rather strange. I used Google Drive API to create a folder in Google Drive and then uploaded a file there. I can retrieve the folder and file using the same API (the code is working fine in all respect). However, when I go to Google Drive Web interface, I can't seem to find the folder or file. The file also doesn't sync to my local drive. Is there a setting in API or elsewhere to set the "visibility" ON?

Thank you in advance.
