Question

I have a script that reads files from a folder and catalogs the contents to a spreadsheet. To avoid duplicates I want to move the files to a different folder (file.addToFolder(newFolder)) which works, however when I try to file.removeFromFolder(formerFolder) I get “cannot find method” which would suggest I am not giving it the right class of object even though removeFromFolder is listed as a member of the File class.

function moveFileToFolder(fileId, targetFolderId,formerFolderId) {
  var targetFolder = DocsList.getFolderById(targetFolderId);
  var file = DocsList.getFileById(fileId);
  file.addToFolder(targetFolder);
  file.removeFromFolder(formerFolderId);
};

What am I doing wrong?

Answer 1

You should get the formerFolder like you get the targetfolder and pass it to the method instead of the formerFolderId.
