Some has made it impossible to read parts of the files, either by applying black pen or a white liquid that covers the text below. "White Out" is a brand name, I believe, but widely used to mean "correction fluid."

In BrE, the brand name which has come to be used as a verb in its own right is "Tippex".

He tippexed out the bits he didn't want anyone to read.

In the last few years, especially - in the UK - since the Freedom of Information Act 2000 - Wikipedia, the free encyclopedia, the word 'redacted' has become quite common. The files were 'heavily redacted'. (Of course, the word existed long before that, but it's become a lot more common recently; and unlike cognates in other languages (e.g. rédacteur) it has the implication of obliterating rather than just editing.)
