With SafeFileManager you can safely transfer files over unreliable media. Often slightly bad RAM-Memory causes bits to fall. SafeFileManager automatically detects bad transfers and starts a re-transfer as often as the file has not been transferred correctly up to retry counts you specify.
You can do many other things with SFM that you can do with a file manager. Deleting and renaming files and directories and creating directories are no problem to do. More functions will be added as development progresses.
