class DriveApp method .getFoldersByName()

DriveApp is the Apps Script service.

.getFoldersByName() is the method name you will see after a dot in your code.

What it does

Finds folders in Drive that match a given name.

Why it's used

  • Locate the 2024 Reports folder across a messy Drive.
  • Route new files into an existing folder by name.

Common errors

  • Forgetting parentheses on getFoldersByName. Write DriveApp.getFoldersByName(), not DriveApp.getFoldersByName or getFoldersByName by itself.
  • Skipping dots between chained calls. Each step needs a dot, like DriveApp.getFileById(id).getFoldersByName().
  • Adding spaces where they do not belong. Write DriveApp.getFoldersByName(), not DriveApp .getFoldersByName(), DriveApp.getFoldersByName (), or DriveApp . getFoldersByName().
  • Wrong capitalization. Use DriveApp and getFoldersByName, not driveapp or getfoldersbyname.
