Hi,

Victor has already given you the answer - you have to use the parent
directory's get_child method.

If you want, you can consult my "Emperor" file manager's deletion code
at
https://github.com/tjol/emperor/blob/master/src/modules/basic_actions/basic_actions.vala#L256

As this is a GUI file manager, the code is more complex - it uses
asynchronous methods, asks the user for confirmation, and does error
handling. The core loop, equivalent to what you've been writing, is
here:
https://github.com/tjol/emperor/blob/master/src/modules/basic_actions/basic_actions.vala#L348
