This PR addresses a bug caused by listing an empty folder.
In order not to leave global variables in the board's memory, we delete objects created during file creation/changes/listing.
If a folder was empty, the
f
variable would not exist and could not be deleted.to reproduce the bug:
During folder creation or navigation this was a non-issue, but trying to upload a file into that folder would hang the editor.
Another minor (but important) change was updating the import to replace
uos
withos
