Overwrite File in Google Drive

Question

I'm using this Google Script:

Gmail2GDrive

and it works like a charm except that I need it to overwrite the existing file as I'm intending to link to it and share it.

How would I need to modify this script?

Answer 1

You can't really overwrite a file in Google Drive. (Not that I am aware of.) Each file has its own unique ID which means the name of the file is kind of irrelevant. (When attempting to override a file in the Windows Explorer terminology.)

That being said I have used this in the past to move files using Google App Script. Hope it helps:

  //Get the ID of the Destination Folder
  var destinationFolder = DriveApp.getFolderById("Your Folder ID");

  //Create a copy of the Merged Sheets Temp and move to the Desitnation Folder.
  DriveApp.getFileById(FileToMove.getId()).makeCopy("Give the File a name", destinationFolder);

  //Move Merged Sheets Temp to Trash
  var tempMergeDocument = DriveApp.getFileById(FileToMove.getId()).setTrashed(true)
