The space containing the deleted files is also now marked as free space so it is available to the system for any new files to be written there instead. If and when that happens, then it becomes too late to recover your deleted files so it is very, very important to not save any new files or data to the device concerned.If the deleted files are on a memory card or USB memory stick, just don't save any new files to it.
