Ghost Writer is an exhibition space created and curated by Camden Segal. Ghost Writer exploits data remanence. When a file is deleted normally only the directions to find the file’s information is actually deleted. None of the information that makes up the file is deleted, only lost. Without directions to find the files, the computer slowly overwrites the deleted file as the user adds files to the hard drive.
Ghost Writer simply downloads a file to computers, then immediately deletes it, so that the computer no longer knows where the data is on the drive. In this way the file is turned into an artificial ghost, an invisible remnant of a file never truly used by the computer or user. This file sits useless either slowly overwritten, or forcefully uncovered using file recovery software such as PhotoRec.
