I have a problem with what I think is a broken link

Question

HEre image attached of one example. index.html and index.html~ appears everytime I finish editing the file. But it does not have any content and it does not go away unless I delete it, but, I am afraid of deleting the actual file.

Answer 1

The index.html~ is meant to be a backup of the file.

When you edit a file with Gedit, Ubuntu saves the original as filename~. The backup file is supposed to reflect what the original file looked like before it was edited.

It doesn't contain a whole backup history. It just keeps the last version of the file for you.
