See Bug 1260606 comment #28 > Likewise, I'd be fine with us firing a special error from FileReader if the > file changed on disk. But I don't think we currently do. If a file was modified after it was selected using INPUT[type=file] from Firefox 45 build FileReader.readAsText(HTML_FORM_INPUT.files[0]) fails. But there is no way in the error handler to identify the reason for the failure. Please provide a mechanism for JavaScript developer to identify failure reason so that s/he can take appropriate action.

I want add one more situation, there will also case where file was deleted from the disk or there is network fault (if file was network, or on removable disk) after user selected it with FORM_INPUT file control.
