The stress and struggle that you experience when a sought file is missing in your expected folder is anybody's guess. When a symbol or character is missing from your visibility while inputting through the visible screen or an unexpected character appears at a space, the effects are worse. The remote manipulator whether an active human or an automated script, may or may not be aware of the scenario at the results end screen. Any amout of harsh mental reactions to the immediate environment will have no useful results either. Thus any input-ouput terminal activity into the internet must be supported by a safety evaluation protocol for the environment, device and the local user.
