Description: Description Select the type: Feature Bug fix Code refactor Documentation BlocksScreen/lib/files.py: Refactored directory/file handling architecture: On WebSocket connection: requests the full file list once via initial_load() On notify_filelist_changed: updates internal state incrementally Emits signals for UI components to react to changes Added comments throughout the code BlocksScreen/lib/panels/mainWindow.py: Handle metadata missing errors and limit retries (timeout after 3 attempts per file) Added comments to clarify logic BlocksScreen/lib/panels/widgets/filesPage.py: Reacts to changes from files.py and adapts the EntryListModel accordingly Added “USB” icon to folders that start with USB- Added comments throughout the code BlocksScreen/lib/utils/list_model.py: Added method remove_item_by_text Added method insert_item to insert an item at a specific index Motivation This refactor improves the file list handling flow by separating full initial loading from incremental updates, which leads to better Modular Design and avoids unnecessary UI refreshes. It also introduces controlled retry logic for missing metadata, enhancing Reliability, and makes the UI clearer by displaying a USB icon for USB‑related folders, improving User Experience. Alongside these functional improvements, the changes enhance Readability and Extensibility of the codebase by organizing logic more cleanly and adding comments throughout the affected modules. Tests Tested on RF50, Missing Unit and Integration Tests, Future work Creating unit and integration tests, and handle of the root_update method called when the gcodes folder is changed
