How to delete a File in Google Drive?

Question

How do I write a Google Apps Script that deletes files?

This finds files:

var ExistingFiles = DocsList.find(fileName);

But Do

Answer 1

This code uses the DocsList Class which is now deprecated.

try this :

function test(){
deleteDocByName('Name-of-the-file-to-delete')
}

function deleteDocByName(fileName){
  var docs=DocsList.find(fileName)
    for(n=0;n

since you can have many docs with the same name I used a for loop to get all the docs in the array of documents and delete them one by one if necessary.

I used a function with the filename as parameter to simplify its use in a script, use test function to try it.

Note : be aware that all files with this name will be trashed (and recoverable ;-)

About the last part of your question about keeping the most recent and deleting the old one, it would be doable (by reading the last accessed date & time) but I think it is a better idea to delete the old file before creating a new one with the same name... far more logical and safe !
