Google App - check if file exists already?

i use this code in upload form (google scripts):

var blob = form.myFile;    
var file = folder.createFile(blob);    
file.setDescription("Uploaded by " + form.myName);

however, i want to check if file exist with same name, then dont upload. How to do that?

Well that's simple enough. All you need to do is use the getFilesByName() and the use the hasNext() to see if any files were found:

var file = DriveApp.getFilesByName('name of file to upload')
var chk = file.hasNext()
if (chk === true) return 1

if a file with the name was found, then hasNext() will return true. That means that we need to stop the script. You can do throw instead of a return, but that is up to you. The whole thing can also be in one line

if DriveApp.getFilesByName('filename').hasNext() === true) return 1
