add exists() method for iCloud file validation

[DevCodeSpace]

Hello @unclezs

Thank you for raising this feature request for the exists() method.

We will implement this in our next version update. The exists() method will allow checking if a file exists in iCloud storage before performing operations, which will help prevent potential errors.

Please feel free to track this enhancement for further implementation updates.

Please add the possibility to check for an existing directory as parameter too. Thanks!
