Diagraphephobia

Diagraphephobia (also known as Delephobia and Cyberdispophobia) 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. This is also known to cause digital hoarding, which isn’t neccisarly as bad as real life hording, but normal “digital hoarders” download lots of data, usually as the goal as archiving. Most diagrephephobes do not do this. They might also hoard physical electronic devices (or only electronic storage media, like cellphones).

Trivia
'''Please do not comment about Friday Night Funkin or Eteled or else you will get a punishment. If you want Friday Night Funkin, click here. If you want eteled, go here.'''
 * 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.
 * If for some reason, any illegal pornography is downloaded on their computer, they would not delete it and would rather get arrested.
 * The maximum extent of this phobia is not being able to press the backspace button to delet a single letter they missed and would rather use the arrow keys to do so or autocorrect.
