System errors are messages that tell you that something is not right http://www.pcerrorsfixer.com/why-you-should-not-ignore-error-509 with your computer’s software or hardware. Most of the time they come with a short description after them that can help you fix the issue. However, not all error codes are created equal. Some error codes can be difficult to comprehend and aren’t helpful. For example an error code that says «file name is too long» probably means your file’s name, or extension is too long for the filesystem to accommodate. In this instance cutting down on the length of your filename or the space available on your hard drive would solve the issue.
Other error codes could be a sign that your system was unable access a device on a hard disk or use a file that did not exist. These errors usually cause your system to stop. You will see a blue screen and an error message indicating the system error.
Some older systems require that information conform to strict formats and can throw an error if there’s even the slightest deviation. Contrary to this, modern systems tend to be more flexible and more tolerant of information that does not conform to the format specified.
