Codeless Reference

where:

Argument	Description
from path	A path identifying file or directory to be copied. The path must start with the root directory of the remote file storage.
to path	A path to a directory where the source file or directory should be copied to. If the directory does not exist, a new one is created.
return URL of the copied directory/file	When this box is checked, the operation returns a URL to the copied file or directory.

Returns the URL to the copied file or directory

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

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.

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