What is an ERSX file? Data file created by Eraser, a Windows program used for securely erasing files and folders from your hard drive; saves a list of erasing tasks as well as the schedule information for when to run each task.

More Information When Eraser removes a file, it also overwrites the file's contents on the hard drive with patterned data that makes the original file unrecoverable. This technique is useful when deleting personal sensitive data, such as passwords, journal documents, and financial records. NOTE: Eraser automatically stores the task list to the [user]\​AppData\​Local\​Eraser\​ directory when you create tasks. The file uses a binary format and is not human readable.
