Diagraphephobia

Diagraphephobia is the fear of deletion/deleting stuff or data loss (deletion, ransomware, overwrite, factory reset, hard drive getting eaten by a dinosaur, etc). It can also be believing that you are living inside a video game or computer simulation, and being afraid that you are going to get deleted from existence. The fear of being deleted is Autodiagraphephobia. Also applies to the fear of having your important documents, photos, or other files deleted and living as a file, photo or a document inside a computer. This phobia may be developed as a side effect of Disposophobia. Some people with Diagrephephobia can't delete any minor file including cache files. Some people with this phobia could delete files if a backup exists.

Trivia

 * Despite having it's namesake related to a song in the Wii Deleted You Friday Night Funkin mod, Diagraphephobia does not have any correlation to Friday Night Funkin' or the Wii Deleted You creepypasta, other than the song going by the same name. For clarification, both the mod and creepypasta's story revolves around the idea of a mii character named Eteled being trapped inside a haunted wii and though he can come back after deletion, it physically and mentally pains him, so that he won't be deleted he purposely scares and disturbs the wii owner as a punishment, if deleted.
