Consider the following file and folder stored in the notes directory:

files_api_copy_file_directotry_2

The example below copies the "monday_food.txt" file to the "grocery" directory. The same operation can be also applied to a folder, not only to a file.

files_api_copy_file_directotry_3

The result of this operation will look as shown below after the Codeless logic runs:
