+| **You delete a file** | Moves its item to the bin after a five-second grace, so a save that replaces a file isn't taken for a delete. A sync that is running when you delete the file doesn't write it back. |
+| **You move or rename a file in the folder** | Keeps its item, even when the move lands while a sync is running, and doesn't write the file back where it was. |
 | **An item is moved to the bin, purged, or leaves the states the search holds** | Removes its file at the next sync. A file you changed since Marfa wrote it stays. |
 | **An item stops matching the search** | Keeps its file, and edits to the file still reach the item. [`marfa folders unmatched`](/guides/keep-folders-running#remove-files-a-folder-keeps-but-no-longer-holds) lists these files. |
 | **You move a file to another folder on the same Mac** | Treats it as the same item, so the folder it left doesn't take the move for a delete. |
